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 vendor’s name. You can also assign a document number manually if you prefer.
To assign document numbers manually:
1. Open Non-PO Receipt Entry.
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).
4. Begin entering the order, starting with the Vendor Number. Refer to the How to enter or change purchase orders information procedure for additional information.
To access the Warehouse/Direct Ship Selection dialog box to create a direct shipment, select 
icon or press F1. If the Non-PO receipt is a direct ship, enter the warehouse that is to be the initiating warehouse. The warehouse entered for a direct ship is stored only to determine where the PO originated; inventory quantities and restocking controls are not affected. This becomes the ship-to address on the purchase order. You can press F4-backup and override the address, or continue to back up to the warehouse prompt.
