Is there a way to insert line items via taPopRcptLineInsert onto an existing receipt? When I try to feed it the desired existing POPRCTNM, I get the error 'Input variable contains a duplicate document (POPRCTNM)". It works of course if I leave the POPRCTNM field empty, but it places each separate transaction on its own receipt and I would like to manage the receipts better than that. Any ideas?
