MB-820 Exam Dumps : Microsoft Dynamics 365 Business Central Developer

 No AL command in User Settings:

The correct solution is to Install the AL Language extension.

This issue arises when the AL Language extension is not installed in Visual Studio Code, which is required to work with AL projects in Business Central.

 Error in the Problems tab:

The correct solution is to Download Symbols.

This error typically occurs when the symbols (metadata for pages, tables, etc.) are not downloaded, and Visual Studio Code cannot resolve the reference to the Customer List page. Downloading symbols should fix the problem.

 Add Clear(PurchaseLine); as a line before line 01 of the code: No

 Add PurchaseLine.SetFilter("Line No."; '>0') as a line after line 06: Yes

 Change the filter on line 06 from a "No." field to a "Document No." field: No

 Remove "not" in line 07: No

 Add Clear(PurchaseLine); as a line before line 01 of the code.

No

You do not need to clear the PurchaseLine record before running the query, because the SetRange filters will take care of setting the correct context.

 Add PurchaseLine.SetFilter("Line No."; '>0') as a line after line 06.

Yes

Adding a SetFilter on the "Line No." field ensures that you're checking for actual purchase lines greater than 0, which are valid lines. This would fix the issue where the check might return false even when lines exist.

 Change the filter on line 06 from a "No." field to a "Document No." field.

No

The filter on the No. field is correct, as it's filtering based on the purchase order number. Changing this to Document No. is unnecessary.

 Remove "not" in line 07.

No

The not in line 07 is necessary because IsEmpty() returns true when no lines are found. To correctly return a boolean indicating whether the purchase order has lines, you need to negate the result of IsEmpty().
