Header fields are used for information that you expect to remain unchanged throughout a single transaction, such as the buyer name, department, or terms. These fields appear in the Header Information section of the purchasing window and the Receiving Information section of the receiving window. Information entered in the header section applies to all detail lines entered on the transaction. By using the Text for heading and Column width fields, you can enter a different heading for a field in the entry and receiving windows and adjust the column widths to what works best for your business.
