Invoice record structure

Information for each invoice record is stored in the invoice header, line detail, and comments.

Section	Description
Invoice header	The invoice header contains information about the invoice as a whole, including the company, process level, and invoice amount. Many fields have default values assigned to the vendor, company, pay group, vendor class, or vendor group. Many of these can be overridden during invoice entry.
Invoice line detail	The invoice line detail contains the item's identifier or match detail key, unit cost, unit of measure, invoice quantity, and extended cost. The extended cost is the total cost of the line and is calculated as the unit cost times the invoice quantity. Invoice line detail is also referred to as item detail or line detail. Line detail is provided from the purchase order and can be specified during invoice entry.
Comments	Comments are additional information you create for the invoice header. You indicate where you want these comments to be displayed or printed. For example, an explanation can be printed on a check to a vendor. Comments are used to put special handling instructions for vendor invoices in the system for internal use only. More than 50 lines of text can be added and formatted using word wrap.
