I've got Sage 50 Premium Accounting. When I go to create an Sales Invoice and I type in the Order no. in the tab they give you, it won't display on the print preview of the invoice, but it will on the print preview of the packing slip. I need to be able to have a customer's P.O # show up on the printed version of an invoice and I figured that the Order no, was the place to input that info. I don't understand why it won't show up on the printed copy that has a place for Order No. Instead of showing the order number I assigned it assigns the same number as the invoice number. Please help!! I'm desperate to move forward from this issue.
