Use the purchasing evidence to decide what each invoice task requires. A saved invoice can still carry a payment block. A received quantity is physical evidence, while the ordered quantity is a supplier commitment. The difference matters when a supplier invoices early or the warehouse receives a partial delivery.
These fresh tasks review matched invoices, quantity shortages, stock and blocked-item reporting. Work each independently. When you calculate a stock quantity, use the current records instead of an earlier example. When you save an invoice, preserve its supplier reference so a duplicate can be recognized later. A payment proposal should exclude a blocked item even when it is due. No new verification rule is introduced in this practice set.
