Account Number .. is Invalid 

A form level error has occurred.

CAUSE: .. does not exist in the Account Master file (F0901) NOTE:

              If you get this error message on a discount amount, it is

              indicating that the account numbers set up in the Automatic

              Accounting Instructions are invalid. The AAI records being

              validated against are PKD/PKL for Accounts Payable and RKD for

              Accounts Receivable. If business unit is not defined in the

              AAI accounts, the program will use the business unit from the

              voucher/invoice. If the error message is on adjustment reason

              in cash receipts, the same holds true about the AAI account
