 The connectedCallback is a lifecycle hook that is invoked when a Lightning web component is inserted into the DOM. It is used to perform any initialization tasks that depend on the component being rendered, such as fetching data, setting up event listeners, or creating timers. The connectedCallback can fire more than once, for example, when a component is moved or rerendered. The connectedCallback should not be used to change the state of a component, such as loading values or setting properties. Use getters and setters instead. The other options are incorrect because they do not describe the purpose of the connectedCallback. References: Lifecycle Hooks | Lightning Web Components Developer Guide, connectedCallback() in Lightning Web Component - Salesforce Diaries, Chapter 23: connnectedCallback() in Lightning Web Component

 The method signature that is used in the Global API’s is ccrz.cc_Output (ccrz.cc_Input input). This signature indicates that the Global API methods take a single input parameter of type ccrz.cc_Input and return an output of type ccrz.cc_Output. These are custom classes that are defined in the cloudcraze managed package and contain various properties and methods for handling the input and output data. For example, ccrz.ccServiceProduct.getProducts(ccrz.cc_Input input) is a Global API method that takes an input object and returns an output object containing product data.

 To make an integration available for selection, a developer must create a RegisteredExternalService record using Workbench and create an Apex class that uses the integration framework. Creating a RegisteredExternalService record using Workbench allows the developer to register their custom integration class as an external service in Salesforce B2B Commerce. The RegisteredExternalService record contains information such as the class name, version, display name, description, and category of the integration class. The category determines where and how the integration class can be used in B2B Commerce, such as ShippingService or TaxService. Creating an Apex class that uses the integration framework allows the developer to define custom logic for integrating with an external service provider’s API or service. The integration framework provides interfaces and classes for various types of integrations, such as shipping, tax, payment, inventory, and freight. The developer can implement these interfaces and classes in their custom Apex class and override their methods with their own logic. Modifying the StoreIntegratedService to map to an Apex class ID using Workbench is not a required step for making an integration available for selection, as it is only used for registering internal services that are provided by Salesforce B2B Commerce out-of-the-box. Entering the integration class name and version in store administration is not a required step either, as it is only used for selecting an existing integration class that has already been registered as an external service. Salesforce References: [B2B Commerce Developer Guide: Integration Framework], [B2B Commerce Developer Guide: RegisteredExternalService Object]

Composition is a key pattern in building Lightning Web Components (LWCs). This approach involves creating small, reusable components that can be assembled to form more complex interfaces. This pattern promotes modularity, reusability, and maintainability in the development of web components, aligning with web standards and best practices.

 A developer needs to make a call to a long running web service which is critical to finalizing their checkout process. The developer should consider the following items in their implementation:

• A new CORS entry may need to be created in Setup. CORS stands for Cross-Origin Resource Sharing, which is a mechanism that allows web browsers to make requests to servers on different domains. If the web service is hosted on a different domain than the B2B Commerce site, the developer may need to add a CORS entry in Setup to allow the browser to access the web service. This entry specifies the origin, path, and method of the request, as well as any headers or cookies that are allowed1.
• A new Named Credential may need to be created in Setup. A Named Credential is a type of metadata that stores the URL and authentication settings of a web service. By using a Named Credential, the developer can avoid hardcoding the web service URL and credentials in their code, and instead reference the Named Credential by name. This makes the code more secure and easier to maintain2.
• An Apex method returning a Continuation will need to be created. A Continuation is a special type of Apex object that allows the developer to make asynchronous calls to long running web services. By using a Continuation, the developer can avoid blocking the main thread and improve the user experience. A Continuation method must return a Continuation object, specify the web service URL and parameters, and register a callback method that handles the response3.

Option D and Option E are incorrect because they are not relevant to the scenario. Option D suggests that the developer should broker the requests to the web service, which means to use an intermediary service that manages the requests and responses. This may be useful for some scenarios, but it is not required for making a call to a long running web service. Option E suggests that the developer shouldcreate a new Remote Site in Setup, which is a way to whitelist the domains that can be accessed from Apex code. However, this is not necessary if the developer uses a Named Credential, which automatically handles the Remote Site setting2. References:

• Set Up CORS
• Named Credentials
• Continuation Class

To ensure that a custom field is available to display on a given page, the Developer needs to override the Service Class that the page uses and update the Service Management in CCAdmin for the given storefront to use this new Service Class. The Service Class is responsible for retrieving and setting data for a given page. The Logic Class is responsible for implementing business logic and validation rules for a given page. Creating a new Service Class or Logic Class is not necessary, as overriding an existing one can achieve the same result. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Service Classes, Logic Classes

To bulk create product data translations via Data Loader, permissions beyond View Setup and Configuration are necessary. "Import Custom Objects" permission is required to import bulk data into Salesforce, including translations for custom objects. "Manage Translations" permission is essential for managing translation workbench settings and importing/exporting translation files, which is crucial for handling product data translations.

A target value of lightning__FlowScreen in metadata allows for a Lightning web component to be used in guided user experiences to gather input and to automatically generate configuration properties for the Lightning web component. The lightning__FlowScreen target value specifies that the component can be used on a flow screen, which is a type of flow element that displays information and collects user input in a flow. A flow is a guided user experience that can automate business processes and guide users through screens, actions, and decisions. By using the lightning__FlowScreen target value, the developer can expose their Lightning web component as a custom screen component that can be added to any flow screen. The developer can also use the @api decorator to expose public properties of their Lightning web component as configuration properties that can be set in Flow Builder. Flow Builder is a tool that allows the developer to create and modify flows using a drag-and-drop interface. A target value of lightning__FlowScreen does not allow the Lightning web component to replace standard functionality in flows and subflows or to be dragged onto a page in Lightning App Builder, as these are not related to the flow screen target value. Salesforce References: Lightning Web Components Developer Guide: Configure Components for Flows, Lightning Web Components Developer Guide: Communicate with Flow, Lightning Flow Developer Guide: Screen Components Basics

Two components in a B2B store template that a developer can use to customize a storefront page are My Lists and Product List. My Lists is a standard component that displays and manages lists of products that customers can create, save, or share in the storefront. A developer can use this component to enable customers to organize their favorite or frequently purchased products into lists and access them easily. Product List is a standard component that displays and filters products from one or more product lists in the storefront. A developer can use this component to showcase products from different categories or collections and allow customers to browse or search for products based on various criteria. Order List is not a component in a B2B store template, but rather an object that stores information about orders placed by customers in the storefront. Address List is not a component either, but rather an object that stores information about addresses associated with customers in the storefront. Salesforce References: [B2B Commerce Developer Guide: My Lists Component], [B2B Commerce Developer Guide: Product List Component], [B2B Commerce Developer Guide: Order List Object], [B2B Commerce Developer Guide: Address List Object]

To enable the ability to add new shipping and billing addresses during checkout, a developer should enable Buyer Managed Contact Point Addresses within the Shipping Address standard component in the Checkout subflow. The Buyer Managed Contact Point Addresses is a feature that allows customers to add, edit, or delete their shipping and billing addresses during checkout. The developer can enable this feature by setting the buyerManagedContactPointAddressesEnabled attribute to true in the Shipping Address standard component in the Checkout subflow. The Shipping Address standard component is a component that displays and collects the shipping address information for the cart or order. The Checkout subflow is a subflow that defines the steps and components for the checkout process in the storefront. Creating a new shipping address checkout subflow that utilizes the Buyer Managed Contact Point Addresses component is not a valid way to enable this feature, as there is no such component as Buyer Managed Contact Point Addresses. Enabling Buyer Managed Contact Point Addresses within Commerce Administration is not a valid way either, as this feature is not configurable in Commerce Administration. Creating a Lightning web component that enables this functionality and replaces the current shipping address screen within the Checkout subflow is not a valid way either, as this is unnecessary and complicated when there is already a standard component that supports this feature. Salesforce References: [B2B Commerce Developer Guide: Buyer Managed Contact Point Addresses], [B2B Commerce Developer Guide: Shipping Address Component], [B2B Commerce Developer Guide: Checkout Subflow]

Two viable ways that a developer can import some new product data contained in a JSON file one time are running a command like: sfdx force:data:tree:import -f NewProducts.json -u and converting the JSON to a CSV file and using Data Loader to import it. Running a command like: sfdx force:data:tree:import -f NewProducts.json -u allows the developer to import data from a JSON file into an org using Salesforce CLI commands. The sfdx force:data:tree:import command is a Salesforce CLI command that imports data into an org using JSON files that conform to the SObject Tree API specification. The SObject Tree API specification is a format that defines how records are represented in JSON files for data import or export. The -f flag specifies the path of the JSON file that contains the data to be imported. The -u flag specifies the username or alias of the org where the data will be imported. Running this command will create records in the org based on the data in the JSON file. Converting theJSON to a CSV file and using Data Loader to import it allows the developer to import data from a CSV file into an org using Data Loader. Data Loader is a tool that allows users to import or export data between Salesforce and CSV files. The developer can use an online converter or a spreadsheet application to convert their JSON file into a CSV file that matches the structure and format of their Salesforce object. The developer can then use Data Loader to import the CSV file into their org and create records based on the data in the CSV file. Converting the JSON to an xlsx file and using Workbench to import it is not a viable way to import some new product data contained in a JSON file one time, as Workbench does not support xlsx files for data import or export. Workbench is a web-based tool that provides access to various Salesforce features and functionalities, such as data manipulation, REST Explorer, and Apex Execute. Running a command like: sfdx force:data;import:bulk -f NewProducts.json -u is not a viable way either, as there is no such command as sfdx force:data;import:bulk. The correct command for importing data using bulk API is sfdx force:data:bulk:upsert. Salesforce References: [Salesforce CLI Command Reference: force:data:tree:import], [Salesforce Developer Tools for Visual Studio Code], [Data Loader Guide: Import Data into Salesforce], [Workbench], [Salesforce CLI Command Reference: force:data:bulk:upsert]

To retrieve metadata about a specific picklist, a developer should use the getPicklistValues wire adapter. The getPicklistValues wire adapter imports data from the @salesforce/ui-api module and returns an object that contains information such as the picklist’s label, value, default value, validity, and controlling field values. The getPicklistMetadataValues wire adapter does not exist. The getPicklistMetadata wire adapter does not exist either. The getPicklist wire adapter does not exist either. Salesforce References: [Lightning Web Components Developer Guide: getPicklistValues], [Lightning Web Components Developer Guide: Import User Interface API]

 To implement a custom child checkout component for a B2B or B2C store created with an LWR template, the developer must implement the CheckoutStep interface from the commerce/checkout module. This interface defines the methods and properties that the child component must have to communicate with the parent checkout component and the checkout data provider. The CheckoutStep interface extends the UseCheckoutComponent interface, which provides the common functionality for all checkout components, such as loading and saving data, reporting validity, and handling errors.

The other options are not correct because:

• A. CheckoutSavable is not a valid interface for a custom child checkout component. There is no such interface in the commerce/checkout module or the Lightning web component framework.
• B. Checkoutoutinterface is not a valid interface for a custom child checkout component. There is no such interface in the commerce/checkout module or the Lightning web component framework.
• C. CustomCheckout is not a valid interface for a custom child checkout component. There is no such interface in the commerce/checkout module or the Lightning web component framework.

• Create a Custom Checkout Component for a B2B or B2C Store (LWR)
• CheckoutStep Interface
• UseCheckoutComponent Interface

You should avoid using ccLog in two scenarios. First, you should avoid using ccLog with System.LoggingLevel.ERROR when passing in a method invocation as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.ERROR, ‘D:something’, myCallToGetMessage(pl) ). This is because if an exception occurs within the method invocation, it will not be caught by ccLog and will cause an unhandled exception on the page. Instead, you should use a try-catch block around the method invocation and log the exception separately. Second, you should avoid using ccLog with System.LoggingLevel.DEBUG when passing in a large collection or object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG, ‘D:myOrderList’, myOrderList), where myOrderList is a list of orders. This is because logging large objects can cause performance issues and consume a lot of heap space. Instead, you should use a loop to log only the relevant fields or properties of the object or collection. You can use ccLog with System.LoggingLevel.WARN when passing in a string as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.WARN, ‘D:something’, ‘Something unexpected occurred: The data we were expecting for pl was not there,’). This is a valid use case for logging a warning message. You can also use ccLog with System.LoggingLevel.DEBUG when passing in a small object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG, ‘D:myOrder’, myOrder), where myOrder is an order object. This is acceptable as long as the object is not too large or complex. Salesforce References: [B2B Commerce Developer Guide: Logging]

The next step that the developer should do after suspecting that recent edits made to a checkout flow have created a defect and having data points available to use as inputs in reproducing the scenario is to open the flow, select Debug, provide the Input values, and select Run. A flow is a type of application that automates a business process by collecting data and performing actions in Salesforce or an external system. A flow can be used to customize the checkout process in the storefront by defining the steps and logic that are executed when a customer places an order. A flow can be edited or modified using Flow Builder, a point-and-click tool that allows developers to create and manage flows. Flow Builder also provides debugging and testing tools that allow developers to run and troubleshoot flows before deploying them. To debug or test a flow, the developer can open the flow in Flow Builder, select Debug from the toolbar, provide the Input values for the flow variables, and select Run. This will execute the flow in debug mode, which simulates how the flow runs in the org with real data. The developer can use debug mode to verify if the flow works as expected or if there are any errors or issues with the flow logic or actions. Open the flow, select Attach to Live Session, provide the session ID, and select Attach is not a valid next step, asit is not a feature or option available in Flow Builder or Salesforce CLI. Attach to Live Session is a feature that allows developers to attach a debugger to a running Apex session and inspect the state of the code execution. Open the flow, select Debug with Inputs, provide the Input values, and select Run is not a valid next step either, as it is not a feature or option available in Flow Builder or Salesforce CLI. Debug with Inputs is a feature that allows developers to debug an Apex class or trigger with predefined input values and breakpoints. Open the flow, select Debug, provide the session ID for replay, and select Run is not a valid next step either, as it is not a feature or option available in Flow Builder or Salesforce CLI. Replay is a feature that allows developers to replay an Apex log file and inspect the state of the code execution at each line. Salesforce References: [B2B Commerce Developer Guide: Customize Checkout Flows], [Salesforce Help: Flow Builder], [Salesforce Help: Debug Your Flows], [Salesforce Developer Blog: Apex Replay Debugger]

A Lightning Web Component (LWC) consists of a minimum of three core files: the template file (.html), the JavaScript file (.js), and the metadata configuration file (.js-meta.xml). These files are essential for defining the structure, functionality, and configuration of the component. For more information, review the Salesforce LWC documentation:Salesforce LWC Documentation.

 The developer should implement the custom component so that it subscribes to events on the lightning_commerce_cartChanged channel using the Lightning Message Service. This is the recommended way to communicate between custom and standard components on the Cart page, as it allows the custom component to receive updates from the standard cart component whenever the cart items or quantities change. The Lightning Message Service is a pub/sub mechanism that enables components to communicate across the DOM, regardless of their namespace, technology, or source. The lightning_commerce_cartChanged channel is a predefined channel that carries information about the cart state, such as the cart ID, the cart items, and the cart total. References: Custom Component APIs, Lightning Message Service, Communicate Across the DOM with Lightning Message Service

 According to the Platform Events Developer Guide, to debug platform events, a developer needs to include the Apex Code and Workflow log levels in the trace flag entry for the Automated Process entity or the overridden user. The Apex Code log level captures the execution of the Apex trigger that subscribes to the platform event. The Workflow log level captures the execution of the event process or the resumed flow interview that subscribes to the platform event. The other log levels are not relevant for debugging platform events. The Database log level captures database operations, such as DML statements and SOQL queries. The Callout log level captures the details of HTTP requests andresponses, such as web service callouts. References: Platform Events Developer Guide, Set Up Debug Logs for Event Subscriptions, Set Up Debug Logging

The error code INSUFFICIENT_ACCESS_OR_READONLY is caused by the cart being no longer in a valid Checkout State during checkout flow customizations. A cart is an object that represents a collection of products and charges that a customer intends to purchase in the storefront. A cart has a Checkout State field that indicates the current state of the checkout process for the cart. The Checkout State can have values such as Draft, InProgress, Completed, or Cancelled. A cart can only be modified or updated when it is in Draft or InProgress state. A cart cannot be modified or updated when it is in Completed or Cancelled state. If an attempt is made to modify or update a cart that is in Completed or Cancelled state, an error with the code INSUFFICIENT_ACCESS_OR_READONLY will be thrown. This error means that the user does not have permission to edit or delete a record because it is read-only or locked. The storefront user does not have access to the Cart Delivery Method object is not a cause of this error code, as it is not related to the cart checkout state or data modification. The Cart Delivery Method object is an object that stores information about the delivery method selected for a cart in the storefront. An error has occurred during the cart shipping charge integration is not a cause of this error code either, as it is not related to the cart checkout state or data modification. The cart shipping charge integration is an integration that calculates and applies shipping charges to a cart based on various factors such as delivery method, location, weight, volume, etc. The storefront user does not have access to custom fields on the Order Delivery Method object is not a cause of this error code either, as it is not related to the cart checkout state or data modification. The Order Delivery Method object is an object that stores information about the delivery method selected for an order summary in the storefront. Salesforce References: B2B Commerce Developer Guide: Cart Object, [B2B Commerce Developer Guide: Cart Delivery Method Object], [B2B Commerce Developer Guide: Order Delivery Method Object], [Salesforce Help: Common Error Messages]

To help troubleshoot and respond to actions in checkout, the developer’s code should listen for CommerceDiagnosticEvents. CommerceDiagnosticEvents is an event that is fired by Salesforce B2B Commerce when an error occurs in the storefront. CommerceDiagnosticEvents contains information about the error, such as error code, error message, error type, and error details. CommerceDiagnosticEvents can be subscribed by other components or services that want to handle or display the error information in different ways. The developer’s code can listen for CommerceDiagnosticEvents using an aura:handler tag in Aura Components or an @wire decorator in Lightning web components. The developer’s code can also use the event information to perform custom logic or actions based on the error, such as logging, reporting, or notifying. CommerceBubbleEvents is not an event that the developer’s code should listen for in checkout, as it is not related to troubleshooting or responding to actions. CommerceBubbleEvents is an event that is fired by Salesforce B2B Commerce when a user interacts with a bubble component in the storefront. A bubble component is a user interface element that displays information or options in a pop-up window when clicked or hovered over. CommerceBubbleEvents contains information about the user interaction, such as bubble name, bubble type, and bubble value. CommerceErrorEvents is not an event that the developer’s code should listen for in checkout either, as it is not related to troubleshooting or responding to actions. CommerceErrorEvents is an event that is fired by Salesforce B2B Commerce when a validation error occurs in the storefront. CommerceErrorEvents contains information about the validation error, such as field name, field label, and error message. CommerceActionEvents is not an event that the developer’s code should listen for in checkout either, as it is not related to troubleshooting or responding to actions. CommerceActionEvents is an event that is fired by Salesforce B2B Commerce when a user performs an action in the storefront. CommerceActionEvents contains information about the user action, such as action name, action type, and action parameters.

The correct answer for how to export data from Salesforce or import data into Salesforce using Salesforce CLI commands is running a command like: sfdx force:data:tree:export -q “SELECT Id, Name FROM Product2” -u “” and sfdx force:data:tree:import -f Product2.json -u “”. The sfdx force:data:tree:export command is a Salesforce CLI command that exports data from an org into JSON files that conform to the SObject Tree API specification. The SObject Tree API specification is a format that defines how records are represented in JSON files for data import or export. The -q flag specifies the SOQL query that selects the records and fields to be exported. The -u flag specifies the username or alias of the org where the data will be exported from. Running this command will generate JSON files that contain the data from the org based on the SOQL query. The sfdx force:data:tree:import command is a Salesforce CLI command that imports data into an org using JSON files that conform to the SObject Tree API specification. The -f flag specifies the path of the JSON file that contains the data to be imported. The -u flag specifies the username or alias of the org where the data will be imported to. Running this command will create records in the org based on the data in the JSON file. Running a command like: sfdx force:data:bulk:export -Product2 -all 0 and sfdx force:data:bulk:import -f Product2.json -all is not a correct answer, as it uses invalid syntax and flags for the sfdx force:data:bulk:export and sfdx force:data:bulk:import commands. The correct syntax and flags for these commands are sfdx force:data:bulk:upsert -s Product2 -f Product2.csv -w 10 -u and sfdx force:data:bulk:status -i -u . Running a command like: sfdx force:data;tree:export -Product2 -all q and sfdx force:data:tree:import -f Product2.json -all is not a correct answer either, as it uses invalid syntax and flags for the sfdx force:data:tree:export and sfdx force:data:tree:import commands. The correct syntax and flags for these commands are sfdx force:data:tree:export -q “SELECT Id, Name FROM Product2” -u and sfdx force:data:tree:import -f Product2.json -u . Running a command like: sfdx force:tree:data:export -q “SELECT Id, Name FROM Product2” -u ® and sfdx force:tree:data:import -f Product2Json -all is not a correct answer either, as there is no such command as sfdx force:tree:data:export or sfdx force:tree:data:import. The correct commands are sfdx force:data:tree:export and sfdx force:data:tree:import. Salesforce References: [Salesforce CLI Command Reference: force:data:tree:export], [Salesforce CLI Command Reference: force:data:tree:import], [Salesforce CLI Command Reference: force:data:bulk], [Salesforce Developer Tools for Visual Studio Code]

Useful debugging information in Salesforce B2B Commerce implementation can be garnered in three ways:

• Enabling the logging token via Admin and subsequently inspecting the logs via the browser console. This will enable logging messages and errors to the browser console, which can be viewed by opening the Developer Tools in the browser. The logging token can be enabled by setting the value of CO.logToken to true in CCAdmin.
• Enabling debugging options for the current user and visually inspecting the Salesforce debug logs. This will enable logging messages and errors to the Salesforce debug logs, which can be viewed by opening the Debug Logs page in Salesforce Setup. The debugging options can be enabled by creating a Debug Level and a Trace Flag for the current user in Salesforce Setup.
• Logging into the community as a system administrator to identify any potential permissions or Visualforce exceptions. This will allow viewing any errors or warnings that may occur on the community pages due to insufficient permissions or Visualforce issues. The system administrator can also access CCAdmin and other tools from within the community. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Logging, Debug Your Code

A valid way of referencing the global cc_api_CartExtension apex class via subscriber code is to use ccrz.cc_api_CartExtension. This is the name of the class that is defined in the cloudcraze managed package. The class is global, so it can be accessed by subscriber code. The other options are either invalid or incorrect. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, API Classes

When creating a tax provider, three things that a developer should consider first are: steps to complete in the tax service, how to handle results, and what to implement. Steps to complete in the tax service are the actions that the developer needs to perform to connect to and use the third-party tax service provider’s API or service. These steps may include authentication, authorization, request formatting, response parsing, error handling, and logging. How to handle results are the actions that the developer needs to perform to process and apply the tax calculation results from the tax service to the cart or order. These actions may include creating or updating cart items with type of Charge and charge type of Tax, applying taxadjustments or exemptions, and displaying tax amounts and details on the storefront. What to implement are the methods that the developer needs to define in their custom Apex class that implements the sfdc_checkout.TaxCalculations interface. The interface provides methods for customizing the tax calculation logic for a cart or an order, such as getTaxRatesAndRules, applyTaxAmountsAndAdjustments, and handleTaxErrorsAndExceptions. Whether to use JSON or XML is not something that the developer should consider first, as it is not a critical or relevant factor for creating a tax provider. It may depend on the format that the tax service provider supports or prefers, but it does not affect the overall functionality or performance of the tax integration. What events to fire in the Lightning web component is not something that the developer should consider first either, as it is not related to creating a tax provider. It may be an optional feature that the developer can add to enhance the user interface or user experience of their storefront, but it does not affect the core logic or functionality of the tax integration. Salesforce References: B2B Commerce Developer Guide: Tax Integration, [B2B Commerce Developer Guide: Tax Calculations Interface]

A price group can be dynamically set by extending the cc_hk_pricing hook. This hook allows modifying the price group based on various factors, such as the user, cart, product, or storefront. For example, the hook can apply a different price group for a specific product category or for a specific user segment.

Two ways that events fired from Lightning web components can be handled are programmatically adding event listeners and attaching handlers to DOM elements. Programmatically adding event listeners is a way of handling events by using JavaScript code to register functions that are invoked when an event occurs. The developer can use methods such as addEventListener or @wire to add event listeners to components or services that fire events. Attaching handlers to DOM elements is a way of handling events by using HTML attributes to bind functions that are invoked when an event occurs. The developer can use attributes such as onclick or onchange to attach handlers to DOM elements that fire events. Adding callbacks to components is not a valid way of handling events fired from Lightning web components, as it is not related to event handling, but rather to asynchronous programming. Listening for all possible events at the document root is not a valid way either, as it is not efficient or recommended for event handling, as it can cause performance issues or conflicts with other event listeners. Salesforce References: [Lightning WebComponents Developer Guide: Handle Events], [Lightning Web Components Developer Guide: Communicate with Events]

Two aspects that are applicable to Page Includes are:

• Standard Visualforce controls such as apex:form should not be used within a page include. This is because the page include is rendered inside an existing Visualforce page that already has a form element. Using another form element inside the page include will cause conflicts and errors. Instead, the page include should use HTML elements or custom components that do not require a form element.
• Page Includes can be configured as Body Includes Begin. This means that the page include will be rendered at the beginning of the body section of the page, before any other content or widgets. This can be useful for adding some custom content or functionality that applies to the whole page, such as a banner, a modal, or a script. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Page Includes

A query containing a subquery is executed. By default, in Salesforce B2B Commerce, “__ccrz” is appended to the subquery name as part of its transformation. This is done to avoid conflicts with the standard Salesforce fields and relationships. For example, SELECT Id, Name, (SELECT Id, Name FROMContacts) FROM Account will be transformed to SELECT Id, Name, (SELECT Id, Name FROM Contacts__ccrz) FROM Account__ccrz. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Query Transformation

For investigating errors during development, Salesforce recommends using the Streaming API Subscription Channel for Commerce Diagnostics Event Logging. This tool allows developers to subscribe to a real-time feed of system events, including errors, which can be crucial for diagnosing and resolving issues during development. The Streaming API provides a robust mechanism for monitoring and debugging by delivering secure, scalable, and customizable event notifications within Salesforce or through external systems. This is outlined in Salesforce documentation related to the Streaming API and its application in commerce diagnostics and event logging.

Two data types that are considered discrete units of work (code units) within a transaction in the debug logs are web service invocation and Apex class. A discrete unit of work (code unit) is a segment of executable code that runs as part of a transaction in Salesforce. A transaction is a sequence of operations that are treated as a single unit of work and are executed under certain isolation and consistency rules. A transaction can consist of one or more discrete units of work (code units) that are executed sequentially or concurrently depending on various factors such as triggers, asynchronous calls, or limits. A debug log is arecord of database operations, system processes, and errors that occur when executing a transaction or running unit tests in Salesforce. A debug log can capture information about each discrete unit of work (code unit) within a transaction, such as its start time, end time, duration, events, variables, and limits. A web service invocation is a type of discrete unit of work (code unit) that involves calling an external web service from Apex code using SOAP or REST protocols. A web service invocation can be synchronous or asynchronous depending on the method used to make the callout. A web service invocation can be captured in a debug log with its details and results. An Apex class is another type of discrete unit of work (code unit) that involves executing Apex code that defines a class with properties and methods. An Apex class can be invoked from various sources such as triggers, Visualforce pages, Lightning components, or API calls. An Apex class can be captured in a debug log with its details and results. A validation rule is not a type of discrete unit of work (code unit) within a transaction in the debug logs, as it is not a segment of executable code but rather a formula expression that defines a business rule for a field or object. A validation rule can be evaluated during a transaction and cause an error if the rule condition is not met, but it cannot be captured as a separate code unit in a debug log. A Lightning component load is not a type of discrete unit of work (code unit) within a transaction in the debug logs either, as it is not a segment of executable code but rather an event that occurs when a Lightning component is rendered on a web page or application. A Lightning component load can be measured by various performance tools such as Lightning Inspector or Lighthouse, but it cannot be captured as a separate code unit in a debug log.

Similar to question 198, when custom code compares external prices with sales prices for cart items and finds them to be the same, the appropriate return value should indicate a successful comparison (such assfdc_checkout.IntegrationStatus.Status.SUCCESS). This signifies that the external prices are aligned with the sales prices, and there are no conflicts.

Three ways to implement custom post Order processing are:

• Extend cc_hk_invoice to handle custom business logic post Order processing. This hook allows modifying the invoice data or performing additional actions after an Order is placed. For example, the hook can send an email notification or update a custom field on the invoice record.
• Use cc_hk_Order.placeTarget to define a new Order Confirmation page which executes additional business logic. This hook allows specifying a custom Visualforce page that will be displayed after an Order is placed. The custom page can include additional business logic or user interface elements.
• Use Process Builder to implement business processes that execute when an Order record is created. Process Builder is a tool that allows creating workflows and actions based on criteria and conditions. For example, Process Builder can create a task, send an email, or update a record when an Order record is created.

To authorize the org for Command Line Interface (CLI) access so the developer can deploy Lightning web components, the developer should run the command: 'sfdx force:auth:web:login -r “https://login.salesforce.com” and then supply the credentials in the browser when it opens. The sfdx force:auth:web:login command is a Salesforce CLI command that authorizes an org using the web server flow. The web server flow is an OAuth 2.0 authentication flow that opens a browser window and prompts the user to log in to Salesforce and allow access to the CLI. The -r flag specifies the login URL of the org, which is https://login.salesforce.com for production or developer orgs. Running this command will open a browser window and ask the developer to enter their username and password for the org. After successfully logging in, the developer will be able to use the CLI to perform various tasks with the org, such as deploying or retrieving metadata, running tests, or executing commands. Running the command: 'sfdx force:login -r “https://login.salesforce.com” is not a valid way to authorize the org for CLI access, as there is no such command as sfdx force:login. Running the command ‘sfdx force:auth:web:login -a “https://login.salesforce.com”’ is not a valid way either, as the -a flag specifies an alias for the org, not a login URL. Running the command ‘sfdx force:auth:web:login -r “https://login.salesforce.com” -username’me@my-new-org.org"’ is not a valid way either, as there is no such flag as -username.

To persist payment information data in the Checkout flow for Salesforce B2B Commerce version 4.2 and beyond, the project needs to trigger the processPayment event and pass in the payment information object as an argument. This event will invoke the processPayment method of the ccServicePayment class, which will validate and process the payment information and return a payment result object. The payment result object will contain the status and details of the payment transaction.

To create custom Lightning web components (LWCs), a developer must take two steps: authorize an org for an SFDX project and deploy a custom component. Authorizing an org for an SFDX project allows the developer to connect to a Salesforce org, such as a scratch org, a sandbox, or a production org, and use it as a development environment. Deploying a custom component allows the developer to push the LWC code from the local project to the org and make it available for use. Creating an Apex class is not a required step for creating custom LWCs, as not all LWCs need to use Apex. Cloning an LWC is not a required stepeither, as it is an optional way to create a new LWC based on an existing one.

The use of a standard Visualforce control such as apex:form is discouraged in Salesforce B2B Commerce page includes and subscriber pages because the CCRZ JavaScript object is not accessible within an apex:form control. The CCRZ JavaScript object is a global object that provides access to various B2B Commerce functions and properties, such as logging, utilities, events, and configuration. Using an apex:form control would prevent the developer from using the CCRZ JavaScript object and its features. Visualforce does not “scope” controls that are present on a page and scope of the control will be set to “ccrz”, as this is not a valid statement. Apex:form does not render DOM components slowly, as this is not a performance issue. JavaScript events are supported within an apex:form control, as this is not a limitation.

The template that will correctly display the details message only when areDetailsVisible becomes true given the following code in a Lightning Web Component is option C. Option C uses the if:true directive to conditionally render a template block based on the value of areDetailsVisible. If areDetailsVisible is true, the template block inside the ), not a self-closing tag (
