When merchandise is received, the vendor invoice is entered on the system. However, there can be invoice information that was not known when the invoice was first entered, such as freight charges or a discount available.
You might also want to change previous entries, or add items to an invoice, or finish entering an invoice if you started earlier but didn’t finish.
This option should only be used to edit a an invoice on which you received merchandise itemized line by line. If you want to edit an invoice for non-merchandise, such as a phone bill, choose Enter or Change Invoices Payable from the accounts payable menu.
