Attachments
We are using 11.5.10.2 and our users work with iProcurment and not core purchasing. When a Requisition is approved it auto-creates an Order, which is also auto-approved (we do not use traditional Buyers).
If a user creates a Requisitions and attaches a document (eg Spreadsheet or Word doc) the attachment remains with the Requisition however it cannot be seen in the Purchase Order. The only attachment being the pdf Order, which is sent to the supplier. Although I cannot be certain, I think the attachment is in fact being created in core purchasing, only to be over-written by the pdf attachment.
