Code changes

Note Always test code fixes in a controlled environment before you apply the fixes to your production computers.
To resolve this problem, follow these steps:

1. Change the code in the ZeroAmountLine function in the Sales Line table (37) as follows:
   
   Existing code

   ...
      IF Type = Type::" " THEN
       EXIT(TRUE);
     IF Quantity = 0 THEN
       EXIT(TRUE);
   
   // Delete the following line.         
     IF ("Unit Price" = 0) OR ("Line Discount %" = 100) THEN
   
       EXIT(TRUE);
     IF QtyType = QtyType::Invoicing THEN
       IF "Qty. to Invoice" = 0 THEN
         EXIT(TRUE);
     EXIT(FALSE);  
   ...

   Replacement code

   ...
       IF Type = Type::" " THEN
       EXIT(TRUE);
     IF Quantity = 0 THEN
       EXIT(TRUE);
   // Add the following line.          
     IF ("Unit Price" = 0) THEN
   
       EXIT(TRUE);
     IF QtyType = QtyType::Invoicing THEN
       IF "Qty. to Invoice" = 0 THEN
         EXIT(TRUE);
     EXIT(FALSE);
   ...

2. Change the code in the UpdateVATOnLines function in the Purchase Line table (39) as follows:
   
   Existing code 1

   ...
        IF FINDSET THEN
       REPEAT
   // Delete the following lines.
