We are in the middle of parallel testing for an acquisition. The PR13.1 converted data provided by the acquired entity's data team erroneously included data in fields mapped to ADDL-TAX-CODE, ADDL-RATE and ADDL-AMOUNT. I am attempting to use Addins to change/delete this information out of PR13.1. When I try to change ADDL-RATE and ADDL-AMOUNT fields to zero, the system tells "Change to deduction code not allowed (_f44r0). Can someone tell me what I am doing wrong?
