3648419 - Auto-applied supplier filter issue in Purchase Order Reference field in fiori app Create Supplier Invoice after 2508 upgrade

After the 2508 upgrade, when creating a supplier invoice with reference to a purchase order in the Fiori app "Create Supplier Invoice," the F4 search help for Purchase Order/Scheduling Agreement includes an additional filter. This filter automatically takes the value of the invoicing party from the header of the supplier invoice. The supplier filter prevents the selection of PO with different supplier (e.g. a head office supplier).
