Using INVOIC01, IDOC posts invoices against POs that weren't sent to vendor
Does anyone have any suggestions on how to prevent the IDOC INVOIC01 invoices from posting against POs that were not originally sent to the vendor?? (BSART = INVO)
For example, vendor (1521) sends an electronic invoice file processed as an IDOC. Vendor 1521 includes an invoice against a PO that was sent to vendor 7549. Since the PO exists, the IDOC posts against it. I want to make this a hard error (a 51 status).
