The system automatically creates a document number once you complete the header. At that point, the document number appears in the title bar along with the customer’s name. You can also assign a document number manually if you prefer.
To create document numbers manually:
1. Open Direct Invoice Entry by choosing Sales Orders-->Invoices-->Direct Invoice or by entering the access code DI.
2. Choose File-->New Document Number from the menu.
3. Enter up to six characters to create a document number. Choose OK or press Enter (CR). The document number appears in the title bar.
4. Begin entering the invoice, starting with the Customer Number.
