Which trigger to implement this?

Posted on by mysamza 358

I am trying to write code on Sales Order's subform;

Quantity Remaining = Quantity - Quantity Shipped - Reserved Quantity

Quantity Remaining is a new field I added by extending the Sales Line table and Sales Order Subform.

This value will be Quantity - Quantity Shipped - Reserved Quantity

However, Quantity Shipped only gets a value once the SO is shipped with the value in Qty to Ship.

I tried writing the followling code on ExtendedSalesLineTable

 trigger OnModify()
    var

    begin
        IF rec."Quantity Shipped" <> 0 then begin
            recSalesLine.SetFilter("No.", Rec."No.");
            recSalesLine.SetRange("Line No.", Rec."Line No.");
            recSalesLine.SetFilter("Document No.", Rec."Document No.");
            if recSalesLine.FindFirst() then begin
                "Quantity Remaining" := (Rec.Quantity - Rec."Quantity Shipped") - rec."Reserved Quantity";
                recSalesLine.Modify();
            end;
        end;
    end;

The problem is, I get Not Available in Rec.Quantity Shipped hence it always show me new field Remaining Quantity as 0.

    Do a subscription to codeunit 90 on

    OnBeforePostUpdateOrderLineModifyTempLine(TempSalesLine,WhseShip,WhseReceive,SuppressCommit);

    Update the TempSalesLine, you will get the updated Quantity Remaining when you post.

    Hello @Teddy Herryanto.

    I attempted your method and here is what I came up with;

    Codeunit 90 does not have OnBeforePostUpdateOrderLineModifyTempLine Event.

    I found it on CodeUnit 80 Sales-Post.

    However upon a little testing, where I just tried to execute  message('Did this execute);

    on OnBeforePostUpdateOrderLineModifyTempLine procedure and posted an SO. It did not show the message so I am assuming the OnBeforePostUpdateOrderLineModifyTempLine did not execute.

    However when I did the same for Sales-post Yes/No and chose for example onafterpost event message for this procedure did execute.

    [EventSubscriber(ObjectType::Codeunit, Codeunit::"Sales-Post", 'OnBeforePostUpdateOrderLineModifyTempLine', '', true, true)]
    procedure MyProcedure(var TempSalesLine: Record "Sales Line"; WhseShip: Boolean; WhseReceive: Boolean; CommitIsSuppressed: Boolean)

    var
        recSalesLine: Record "Sales Line";
    begin
       
        TempSalesLine."Quantity Remaining" := recSalesLine."Quantity Shipped" - recSalesLine.Quantity;
     
    end;

    Hi Mesam,

    You can write a local procedure say UpdateRemainingQty where you write the logic.

    Then on validate trigger of all the 3 fields you call the local procedure.

    And instead of creating a variable and not using it anywhere

    Simply write 

    Rec.QuantityRemaining := Rec.Quantity - Rec.QuantityShipped - Rec.QuantityReserved;

    As you don't need to write Rec.Modify.

    If the page doesn't refresh immediately simply use CurrPage.Update.

    Sorry, it is codeunit 80.

    You can't do it like that because the variable recSalesLine is empty.

    Do it like this. You don't need new variable.

    TempSalesLine."Quantity Remaining" := TempSalesLine."Quantity Shipped" - TempSalesLine.Quantity;

    I did the following and it worked!

    [EventSubscriber(ObjectType::Codeunit, Codeunit::"Sales-Post (Yes/No)", 'OnAfterPost', '', true, true)]

       procedure MyProcedure(var SalesHeader: Record "Sales Header")

       var

           recSalesLine: Record "Sales Line";

           nocode: Code[20];

       begin

           nocode := SalesHeader."No.";

           recSalesLine.SetFilter("Document Type", 'Order');

           recSalesLine.SetFilter("Document No.", nocode);

           if recSalesLine.FindSet() then begin

               recSalesLine."Quantity Remaining" := recSalesLine.Quantity - recSalesLine."Quantity Shipped" - recSalesLine."Reserved Quantity";

               recSalesLine.Modify();

           end;

       end;

    Hello, I tried your method and so did I continue making the event/subscribe method work as mentioned by @Teddy and it worked! Posted the code below if you want to have a look! Thanks though!
