Each purchase order must be given a unique code. A purchase order code can be used only once; an attempt to duplicate a code is not allowed by the system. The purchase order code need not be numeric, but it must end in a numeric sequence if the automatic numbering option is going to be used.
Seqno is the method for automatically numbering orders. This method assigns each new order a number that is one greater than the last order number stored.
Seqno assigns numbers based only on the current session. For example, if the first purchase order entered is TL4W393, then the next purchase order is assigned the number TL4W394. The number can be manually changed. Seqno does not remember numbers from one keying session to the next. This means the numbering sequence must be kept track of between sessions. This numbering sequence is designed for keying orders from pre-numbered order forms.
The Purchase Order system comes with the automatic numbering option turned on. Every time you add a purchase order and press the RETURN key in an empty P.O. No. field, the next purchase order in sequence is displayed. To disable this feature, use bookkit to modify the purchase order screen. Change the P.O. No. field so that the User Edit flag is set to no, and the Edit Name field is blank.
