We have business scenario where we have many GRN for single PO. We pay 100% advance and then clear the invoice with bill receive.But we are facing the issue with run time error as time out on vendor clearing for these invoices and with advance. Same we have raise to SAP but they said this is due to long chain of documents as the GRN I said and suggested snote 1419567. But now how I could clear these vendors.Any suggestion from experts.
