The VAT rounding works incorrectly for the corrective entries on sales/purchase documents in the Czech version of Microsoft Dynamics NAV 2009 R2

This article applies to Microsoft Dynamics NAV for the Czech (cz) region.

Symptoms

In the Czech version of Microsoft Dynamics NAV 2009 R2, the system calculates the VAT rounding for the corrective entries on sales/purchase documents. This problem occurs when the system is rounding the invoices and VAT to whole numbers.

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 RoundAmount function in the Sales-Post codeunit (80) as follows:
    Add a text constant as follows:
    Text054 : TextConst 'ENU=%1 %2 must have zero VAT setup.'
    Existing code

    ...
    IF ("VAT Calculation Type" = "VAT Calculation Type"::"Normal VAT") OR
    ("VAT Calculation Type" = "VAT Calculation Type"::"Reverse Charge VAT")
    THEN BEGIN
    GetCurrency;
    GLSetup.GET;
    GLSetup.GetRoundingParamentersLCY(Currency,RoundingPrecisionLCY,RoundingDirectionLCY);

    IF SalesHeader."Prices Including VAT" THEN
    ...

    Replacement code

    ...
    IF ("VAT Calculation Type" = "VAT Calculation Type"::"Normal VAT") OR
    ("VAT Calculation Type" = "VAT Calculation Type"::"Reverse Charge VAT")
    THEN BEGIN
    GetCurrency;
    // Add the following lines.
    IF "System-Created Entry" THEN BEGIN
    RoundingPrecisionLCY := Currency."Amount Rounding Precision";
    RoundingDirectionLCY := Currency.VATRoundingDirection;
    END ELSE BEGIN
    // End of the added lines.

    GLSetup.GET;
    GLSetup.GetRoundingParamentersLCY(Currency,RoundingPrecisionLCY,RoundingDirectionLCY);
    // Add the following line.
    END;

    IF SalesHeader."Prices Including VAT" THEN
    ...
  2. Change the code in the InvoiceRounding function in the Sales-Post codeunit (80) as follows:
    Delete the following local variables:

    • Name: RoundingPrecision; DataType: Decimal

    • Name: RoundingDirection; DataType: Text[1]

    Add the following local variables:

    • Name: VATPostingSetup; DataType: Record (325)

    Existing code 1

    ...
    // Delete the following line.

    InvoiceRoundingAmount :=
    -ROUND(
    TotalSalesLine."Amount Including VAT" -
    ROUND(
    TotalSalesLine."Amount Including VAT",
    Currency."Invoice Rounding Precision",
    Currency.InvoiceRoundingDirection),
    // Delete the following line.
    RoundingPrecision);

    IF InvoiceRoundingAmount <>0 THEN BEGIN
    CustPostingGr.GET(SalesHeader."Customer Posting Group");
    CustPostingGr.TESTFIELD("Invoice Rounding Account");

    WITH SalesLine DO BEGIN
    ...

    Replacement code 1

    TotalSalesLine."Amount Including VAT",
    Currency."Invoice Rounding Precision",
    Currency.InvoiceRoundingDirection),

    // Add the following line.
    Currency."Amount Rounding Precision");

    IF InvoiceRoundingAmount <> 0 THEN BEGIN
    CustPostingGr.GET(SalesHeader."Customer Posting Group");

    ...
    IF ("VAT Calculation Type" = "VAT Calculation Type"::"Normal VAT") OR
    ("VAT Calculation Type" = "VAT Calculation Type"::"Reverse Charge VAT")

    GLSetup.GET;
    GLSetup.GetRoundingParamentersLCY(Currency,RoundingPrecisionLCY,RoundingDirectionLCY);

    IF PurchHeader."Prices Including VAT" THEN
    ...

    Replacement code

    ...
    IF ("VAT Calculation Type" = "VAT Calculation Type"::"Normal VAT") OR

    RoundingDirectionLCY := Currency.VATRoundingDirection;
    END ELSE BEGIN
    // End of the added lines.
    GLSetup.GET;
