Hello

One of our customer , want in Incoming Payments documents row level , a column that display all Sales order related to the invoice .

The incoming payments documents only display Invoice to be paid and it's difficult for our customer to see which Invoice is related to a specific sales order

So i created an UDF called COM and i want this UDF to show all ORDR related to the Invoice ID from the same line num .

Can you please help ?
