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.

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.

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.
