SummarySupplier Portal - Supplier User need add a Attachment in the Purchase Order
With Standard Roles, the Provider does not have access to add a Attachment in the P.O.
The supplier user needs to attach a doc (PDF / XML / XLS / others) either in the PO header or in the same PO line, thus sending, for example, the Invoice PDF issued by the supplier, so that the user of the system can associate the Invoice with the PO and later with Invoice.
The call at Oracle states that this need is a request for future improvement. (very future).
