I defined an operational subcontract for production and linked the work order to the project. When I send the intermediate inventory to the subcontractor, a purchase requisition is created. The relevant requisition line appears to be linked to the project, but it is not linked to the project in preprocessing. The project value is mandatory for the relevant account in the company's accounting settings. Therefore, I receive an error when entering the order on the manual supplier invoice screen. Why doesn't the link appear in preprocessing for purchasing even though I linked the project to the work order? I request your assistance.
