You can match a single invoice to multiple purchase order shipments or you can match multiple invoices to a single purchase order shipment. Payables ensures that you match only to purchase orders for the supplier on the invoice and that the purchase order and invoice currency match.
When you match an invoice to a purchase order, Payables creates invoice distributions using the purchase order distribution accounting information. You cannot delete invoice distributions created through matching. If you incorrectly match an invoice to a purchase order, you must cancel the invoice or reverse the individual distributions to cancel the match.
