Is there a place on a PO where notes can be entered which Accounts Payable can see? For example, If I want to let AP know details about why there is a PO line ordering a part, and another line returning that part, and then another line re-ordering that part. Sure, I could send them an email and tell them, but is there a way for them to see notes when they are entering invoices against a certain PO or PO line?
