The top half or “header” section of the program is used to enter information that applies to the entire accounts payable invoice being processed. This information includes the vendor name and address, the invoice number, the PO (purchase order) number that the invoice is associated with, the invoice amount, invoice date, invoice payment terms and taxcode and other information. Some of the information that is displayed defaults from the Vendor record that is selected in the program.
The header section also displays some information which cannot be edited such as the operator initials, and the year, period and division being used to post the invoice to the general ledger.
You should verify or change the displayed information as required before entering the distribution lines for the invoice.
