GR-Based Invoice Verification
In GR-based invoice verification, a separate invoice item is created for each delivered partial quantity. If you make the allocation with the PO, the system can propose more than one invoice item as a default if more than one partial delivery has been posted for a PO item. If you make the allocation using the delivery note, the system proposes the PO items from this GR along with the quantities posted in this GR.
In GR-based invoice verification, the invoice quantity should not be greater than the actual delivered quantity. However, it is possible to post a larger invoice amount. If doing so, you must be aware that you cannot reassign invoices from one GR to another.
In GR-based invoice verification, you can assign each invoice item uniquely to a GR item. GRs and invoices are matched up in the PO history.
