Symptoms


When you enter an invoice line for the general ledger account that is specified as an invoice rounding account in the customer posting group in Microsoft Dynamics NAV 2009, the value-added tax (VAT) amount is calculated incorrectly. The VAT amount for the invoice rounding account in the general ledger entry should be zero.
This problem occurs in the following products:

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. Create a new GetCPGInvRoundAcc function that uses the Code type for the return value (Lenght 20) in the Sales Line table (37). To create this function, follow these steps:
    1. Add a new local variable, and then specify the variable as follows:
      • NameCust@1012
      • DataTypeRecord
      • Subtype: Customer
    2. Add a new local variable, and then specify the variable as follows:
      • NameCustPostingGroup@1013
      • DataTypeRecord
      • Subtype: Customer Posting Group
    3. Add a new local variable, and then specify the variable as follows:
      • NameCustTemplate@1014
      • DataTypeRecord
      • Subtype: Customer Template
    4. Add a new local variable, and then specify the variable as follows:
      • NameSalesSetup@1008
      • DataTypeRecord
      • Subtype: Sales & Receivables Setup
    5. Add the code as follows:
      SalesSetup.GET;
      IF SalesSetup."Invoice Rounding" THEN BEGIN
      IF Cust.GET(SalesHeader."Bill-to Customer No.") THEN
      CustPostingGroup.GET(Cust."Customer Posting Group")
      ELSE
      IF CustTemplate.GET(SalesHeader."Sell-to Customer Template Code") THEN
      CustPostingGroup.GET(CustTemplate."Customer Posting Group");
      END;
      EXIT(CustPostingGroup."Invoice Rounding Account");
  2. Delete the following local variables in the CalcVATAmountLines function in the Sales Line table (37):
    • Cust@1012
    • CustPostingGroup@1013
    • CustTemplate@1014
  3. Change the code in the CalcVATAmountLines function in the Sales Line table (37) as follows:
    Existing code

    WITH SalesLine DO BEGIN
    SETRANGE("Document Type",SalesHeader."Document Type");
    SETRANGE("Document No.",SalesHeader."No.");
    SalesSetup.GET;
    IF SalesSetup."Invoice Rounding" THEN BEGIN
    IF Cust.GET(SalesHeader."Bill-to Customer No.") THEN
    CustPostingGroup.GET(Cust."Customer Posting Group")
    ELSE
    IF CustTemplate.GET(SalesHeader."Sell-to Customer Template Code") THEN
    CustPostingGroup.GET(CustTemplate."Customer Posting Group");
    END;
    IF FINDSET THEN
    REPEAT
    IF NOT ZeroAmountLine(QtyType) THEN BEGIN
    IF (Type = Type::"G/L Account") AND NOT "Prepayment Line" THEN
    RoundingLineInserted := ("No." = CustPostingGroup."Invoice Rounding Account") OR RoundingLineInserted;
    IF "VAT Calculation Type" IN
    ["VAT Calculation Type"::"Reverse Charge VAT","VAT Calculation Type"::"Sales Tax"]
    Replacement code

    WITH SalesLine DO BEGIN
    SETRANGE("Document Type",SalesHeader."Document Type");
    SETRANGE("Document No.",SalesHeader."No.");
    IF FINDSET THEN
    REPEAT
    IF NOT ZeroAmountLine(QtyType) THEN BEGIN
    IF (Type = Type::"G/L Account") AND NOT "Prepayment Line" THEN
    RoundingLineInserted := ("No." = GetCPGInvRoundAcc) OR RoundingLineInserted;
    IF "VAT Calculation Type" IN
    ["VAT Calculation Type"::"Reverse Charge VAT","VAT Calculation Type"::"Sales Tax"]
  4. Create a new GetVPGInvRoundAcc function that uses the Code type (Lenght 20) for the return value in the Purchase Line table (39). To create this function, follow these steps:
    1. Add a new local variable, and then specify the variable as follows:
      • NameVendor@1000
      • DataTypeRecord
      • Subtype: Vendor
    2. Add a new local variable, and then specify the variable as follows:
      • NameVendorPostingGroup@1001
      • DataTypeRecord
      • Subtype: Vendor Posting Group
    3. Add a new local variable, and then specify the variable as follows:
      • NamePurchSetup@1002
      • DataTypeRecord
      • Subtype: Purchase & Payables Setup
    4. Add the code  as follows:
      PurchSetup.GET;  
      IF PurchSetup."Invoice Rounding" THEN
      IF Vendor.GET(PurchHeader."Pay-to Vendor No.") THEN
      VendorPostingGroup.GET(Vendor."Vendor Posting Group");
      EXIT(VendorPostingGroup."Invoice Rounding Account");

  5. Delete the following local variables in the CalcVATAmountLines function in the Purchase Line table (39):
    • Vendor@1012
    • VendorPostingGroup@1013
  6. Change the code in the CalcVATAmountLines function in the Purchase Line table (39):
    Existing code

    WITH PurchLine DO BEGIN
    SETRANGE("Document Type",PurchHeader."Document Type");
    SETRANGE("Document No.",PurchHeader."No.");
    PurchSetup.GET;
    IF PurchSetup."Invoice Rounding" THEN BEGIN
    Vendor.GET(PurchHeader."Pay-to Vendor No.");
    VendorPostingGroup.GET(Vendor."Vendor Posting Group");
    END;
    IF FINDSET THEN
    REPEAT
    IF NOT ZeroAmountLine(QtyType) THEN BEGIN
    IF (Type = Type::"G/L Account") AND NOT "Prepayment Line" THEN
    RoundingLineInserted := ("No." = VendorPostingGroup."Invoice Rounding Account") OR RoundingLineInserted;
    IF "VAT Calculation Type" IN
    ["VAT Calculation Type"::"Reverse Charge VAT","VAT Calculation Type"::"Sales Tax"]
    Replacement code

    WITH PurchLine DO BEGIN
    SETRANGE("Document Type",PurchHeader."Document Type");
    SETRANGE("Document No.",PurchHeader."No.");
    IF FINDSET THEN
    REPEAT
    IF NOT ZeroAmountLine(QtyType) THEN BEGIN
    IF (Type = Type::"G/L Account") AND NOT "Prepayment Line" THEN
    RoundingLineInserted := ("No." = GetVPGInvRoundAcc) OR RoundingLineInserted;
    IF "VAT Calculation Type" IN
    ["VAT Calculation Type"::"Reverse Charge VAT","VAT Calculation Type"::"Sales Tax"]
