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. Add a new PrepmtAmtToDeduct( PricesIncludingVAT: Boolean; PrepaymentPct: Decimal) : Decimal function in the Sales Line table (37). To do this, follow these steps:

   1. Add a local variable, and then specify the variable as follows:

      • Name: VATFactor

      • DataType: Decimal

   2. Add the code as follows:

      IF PricesIncludingVAT THEN
      VATFactor := (1 + "VAT %" / 100)
      ELSE
      VATFactor := 1;
      EXIT(
      ROUND(
      ROUND(
      ROUND(
      ROUND("Unit Price" * "Qty. to Invoice",Currency."Amount Rounding Precision") *
      (1 - ("Line Discount %" / 100)),Currency."Amount Rounding Precision") *
      (PrepaymentPct / 100) / VATFactor,Currency."Amount Rounding Precision") * VATFactor,Currency."Amount Rounding Precision"));
      

2. Change the CalcPrepaymentToDeduct function in the Sales Line table (37). To do this, follow these steps:

   1. Delete the following local variables:

      PrepmtPct: Decimal;
      AbsoluteAdvCorrection: Boolean;
      

   2. Add the following local variables:

      TotalPrepmtAmtToDeduct: Decimal;
      HundredPct: Decimal;
      

   3. Replace the code as follows:

      IF (Quantity - "Quantity Invoiced") <> 0 THEN BEGIN
      TotalPrepmtAmtToDeduct := "Prepmt. Amt. Inv." - "Prepmt Amt Deducted";
      GetSalesHeader;
      IF SalesHeader."Prepayment Type" = SalesHeader."Prepayment Type"::Advance THEN BEGIN
      VATPostingSetup.GET("VAT Bus. Posting Group","VAT Prod. Posting Group");
      CASE VATPostingSetup."Adv. Invoice Correction Type" OF
      VATPostingSetup."Adv. Invoice Correction Type"::Percentage:
      "Prepmt Amt to Deduct" :=
      ROUND("Qty. to Invoice" / (Quantity - "Quantity Invoiced") *
      TotalPrepmtAmtToDeduct,Currency."Amount Rounding Precision");
      VATPostingSetup."Adv. Invoice Correction Type"::Absolute:
      BEGIN
      HundredPct := 100;
      "Prepmt Amt to Deduct" := PrepmtAmtToDeduct(SalesHeader."Prices Including VAT",HundredPct);
      IF "Prepmt Amt to Deduct" > TotalPrepmtAmtToDeduct THEN
      "Prepmt Amt to Deduct" := TotalPrepmtAmtToDeduct;
      END;
      VATPostingSetup."Adv. Invoice Correction Type"::"Fully Invoiced":
      IF "Qty. to Invoice" = Quantity - "Quantity Invoiced" THEN
      "Prepmt Amt to Deduct" := TotalPrepmtAmtToDeduct
      ELSE
      "Prepmt Amt to Deduct" := 0;
      END;
      END ELSE
      "Prepmt Amt to Deduct" := PrepmtAmtToDeduct(SalesHeader."Prices Including VAT","Prepayment %");
      END ELSE
      "Prepmt Amt to Deduct" := 0
      

3. Add a new PrepmtAmtToDeduct( PricesIncludingVAT: Boolean; PrepaymentPct: Decimal) : Decimal function in the Purchase Line table (39). To do this, follow these steps:

   1. Add a local variable, and then specify the variable as follows:

      • Name: VATFactor

      • DataType: Decimal

   2. Add the code as follows:

      IF PricesIncludingVAT THEN
      VATFactor := (1 + "VAT %" / 100)
      ELSE
      VATFactor := 1;
      EXIT(
      ROUND(
      ROUND(
      ROUND(
      ROUND("Unit Cost" * "Qty. to Invoice",Currency."Amount Rounding Precision") *
      (1 - ("Line Discount %" / 100)),Currency."Amount Rounding Precision") *
