To create a query that assigns vendors to items in Business Central, use the following code blocks in sequence:

dataitem(Vendor; Vendor)

dataitem(Item; Item)

DataItemLink = "Vendor No." = Item.Vendor_No;

Creating a query:In Business Central, a query object is used to combine data from multiple tables. You start by specifying each table as a data item. In this case, you would start with the Vendor table and then the Item table. After specifying the data items, you need to link them together. The DataItemLink property is used to establish a relationship between two data items based on a common field. Here, you are linking the Vendor and Item tables on the "Vendor No." field, which is present in both tables. This link ensures that the query will return a dataset that includes related records from both tables based on the vendor number. The order of the code blocks ensures the logical flow and relationships between tables as required for the query.

Here’s the process to follow in the correct sequence:

In Visual Studio Code, locate the Ext Standard Sales - Invoice report extension from your application.

The first step is to locate the specific extension you're working with so you can modify or inspect its code.

Search where the NewTotalVATBaseLCY variable is being calculated and set a breakpoint on the line.

To debug the issue, you need to place a breakpoint on the line where the NewTotalVATBaseLCY is calculated.

Start debugging.

Once the breakpoint is set, you begin the debugging process to examine the values and code execution.

Use the step-over functionality.

After starting the debugging, you will use the step-over functionality to move through the code line by line and observe the values of the variables.

To meet the XMLport configuration requirements:

Link the child table to its parent: Use the OnAfterGetRecord trigger.

Display a confirmation message after the XMLport runs: Use the OnPostXMLPort trigger.

In Business Central, when you are developing an XMLport for data export, triggers are used to perform actions at different stages of the XMLport's operation:

OnAfterGetRecord Trigger:This trigger fires after a record is retrieved from the database but before it is processed for output in the XMLport. It is the ideal place to link child table records to their parent because you have access to the current record that can be used to set filters or modify data in the child table before it is written to the XML file.

OnPostXMLPort Trigger:This trigger fires after the XMLport has finished processing all records. It is the correct place to display a confirmation message because it ensures that the message will appear after the entire XMLport operation is complete. Here, you can use application-specific functions to show the message, such as MESSAGE function in AL code.

By placing the appropriate triggers in these positions, you can ensure that the XMLport will link the child records to their parent records during the data export process and will notify the user with a confirmation message once the operation is successfully completed.
