How to update TCA Codes, and Inheriting those changes on a cross way, over AR,AP,LE?

Hi Team – I hope you`re doing safe at home!

I come to you since We are working on Oracle R12, and due to a local tax statutory requirement, we need to update some TCA Codes and Names, and then to have them inherited into AR Customers, AP Vendors and Legal Entities addresses, using those TCA codes.

We were testing the process, and let me show you what we did till now and wht we got:

1. We were updating manually TCA Codes and names, and this worked smoothly.

2. After that, received a message to run GEOGRAPHY NAME REFERENCING PROGRAM, I  assume to spread those changes all over the Subledgers.
