When an invoice is printed it is common to provide the customer with information about back ordered items. This is done by printing a section at the end of the invoice listing the open items on the sales order.
The back ordered quantity is not printed on the invoice line for the following reasons.
• The invoice is printed from the stored invoice data, only those lines that were actually shipped (invoiced) are available to print. Only invoiced lines are stored to economize on disk space.
• An order can be shipped from numerous locations, and since an invoice is printed only for the shipment of goods from one location, the Back order information should reflect the total amount on Back order, not just the goods from one location.
