Address Book Category Codes (01/01 through 01/30)

You must define an address book category code to identify the suppliers and customers who issue or receive credit invoices.

You can use any category code, but you must specify the number of the category code that you are using in the General Constants program (P76A20).

You must set up a code for the category code that you specify. You can use any code. If the supplier or customer has a code other than blank in this category code, the system assumes that a credit invoice must be issued.
