Typically, customers enter PO Receipts starting/beginning with the PO# for which they're doing a receipt (not by entering a Vendor). Often, a person in receiving will have access to the PO (via a label, etc.) before seeing the Vendor. This would speed the process in that by entering a PO number, the vendor and PO lines could automatically come in to the grid. This would eliminate steps and align the process more closely with real-world experiences. Right now, it's at least 3 steps/clicks just to add a PO line to the receipt screen.
