When you post goods receipts, there are several ways of finding the associated purchase orders.

If you establish a link via the PO number itself, the relationship is unique (i.e. one goods receipt (GR) against one purchase order).

If you enter the number of the inbound delivery, the system selects all purchase orders containing this number and suggests the notified quantities for the GR document.

If you enter the transport identification code, the system carries out two steps. In the first one it selects all existing inbound deliveries relating to the transport ID. In the second, it selects all Pos relating to the inbound deliveries and then suggests the open notified quantities for the GR document.

If you wish to match up Grs against Pos via the inbound-delivery number or the transport identification code, the inbound delivery must exist as a separate document.
