    use this code on onInsert trigger of sales Line Table and then execute
     
    trigger OnInsert()
    var
    SalesHeader: Record "Sales Header";
    begin
    SalesHeader.Get("Document Type", "Document No.");
    "My Field" := SalesHeader."My Field";

    This looks wrong
     

     
    Should be Rec_SalesLine."Req.Delivery Date" as "Req. Delivery Date" is referring to Rec."Req. Delivery Date" 
     
    I think you're setting the header to itself.

    Hi Yunzhu,
    I have write the same logic on insert trigger on sales line table, but still is not working. Is any other way to do this?

    Hi Sir,
     
    It is high recommended that you can troubleshoot in the AL code to identify the root cause of the issue, you can set up break points in the specific lines.
     
    Best Regards,
    Judy

    This is because your code only exists in the OnValidate trigger of Req.Delivery Date field. When you add new Sales Line, the trigger of this field is not executed.
    I think you need to add similar logic in the Sales Line's OnInsert (Table) Trigger. This should solve the problem.
     
    Hope this helps.
    Thanks.
