Add the total of a column on a list page

Posted on by BchM 92

On the "Purchase Invoices" page, I want to create a "Totals" section, where the "Amount" and "Amount including VAT" fields of all records are added. To achieve this, I am using the following code:

trigger OnAfterGetCurrRecord()
    var
        PurchaseHeader: Record "Purchase Header";
    begin
        PurchaseHeader.CopyFilters(Rec);
        PurchaseHeader.CalcSums(Amount, "Amount Including VAT");
        TotalAmount := PurchaseHeader.Amount;
        TotalAmountIncludingVAT := PurchaseHeader."Amount Including VAT";
    end;
But it doesn't work, variables always appear in "0". Use this same code in a page created by myself and there if it worked, do I have to change something as it is a default page or am I making a mistake? Some alternative?

    Hi, just adding some info.

    If you need to sum all the invoices on the page, please refer to Natin's code.

    If you just need the total of the current invoice, these are the standard fields, you just need to display them on the page.

    Hope this helps.
    Thanks.

    Hi

    you can also create a function within the page that performs the calculation you want to obtain and create a section where you can insert your function that will output your two fields

    Hi,

    I think you should think about your requirement once again, if you are thinking to sum of all the records amount and show, so I would suggest please use the Fact box and in the fact box do the sum of all records and show the total amount of all the records while opening.

    Factbox

    trigger OnOpenPage()

       var

           PurchaseHeader: Record "Purchase Header";

       begin

           PurchaseHeader.reset;

           PurchaseHeader.setrange("Document Type",PurchaseHeader."Document Type"::Invoice);

           PurchaseHeader.setloadfields(Amount, "Amount Including VAT");

           if PurchaseHeader.findset then

           begin

                 PurchaseHeader.CalcSums(Amount, "Amount Including VAT");

                 TotalAmount := PurchaseHeader.Amount;

                 TotalAmountIncludingVAT := PurchaseHeader."Amount Including VAT";

           end;

       end;
