Handling of mismatches between POs and invoices

Summary: Business requirement (UK local authority) - the system must inform requester to add/remove item(s) on an existing PO and cancel the old line(s), and then carry out auto matching against new details.

Content (required): When invoice comes with added lines, requesters would be required to edit the PO appropriately and once carried out the next scheduled auto run of the matching process will progress payment where appropriate. Amendments picked up during the next matching process should be automated once the editing is done as is the case currently and for all other amendments. Currently when mismatches happen users edit POs with automatic run matching determining progression to payment run or to remain on hold - this seems to be impossible in Oracle Fusion.
