When a Purchase Order (PO) has an attachment and the full quantity is received (e.g., 50 units), but invoicing is done in partial quantities, the attachment is not carried over to the intermediate partial invoices. It only appears on the final invoice that completes (closes) the PO.

This behavior causes inconsistency in documentation, especially for businesses that invoice in multiple stages. The expectation is that any attachments associated with the original PO (e.g., vendor documents, terms, specifications) should appear on all posted invoices related to that PO, regardless of whether the invoice is partial or final.

Proposed Improvement:

Change the system behavior so that PO attachments are inherited by each posted purchase invoice document, ensuring full traceability and consistency throughout the invoicing process.
