P.O. NO.

P.O. NO. is used to record the purchase order number in ObjAcct and is supplied to the vendor to track your order within the vendor's system.  A unique P.O. NO. is required for each purchase order.

If you leave the field blank, when you save the purchase order, the next available number for the AP Account will be assigned using the Last Document Nbr in Chart of Accounts. 

You may assign the number yourself and the Last Document Nbr in Chart of Accounts for the AP Account will be updated with the value in P.O. NO., if the purchase order number is greater than the current purchase order number stored in Last Document Nbr.
