Start from D365, Microsoft has a design change to stop the project purchase order posting if the relevant project is finished. This design change is not suitable for the business scenario: 1. The project had received the items\services from vendor, 2. The project is finished, 3. Then received the finial purchase invoice form the vendor. With the new design, user will need to keep the project open until vendor give the invoice, which may causes a lot of challenge for the users.
