Tax code percentage change in existing tax code

[former_member308499]

Hi All,

I have scenario where I need to change tax percentage in the existing tax code which was used 12 year back. I saw no of posts and information where SAP is suggesting not to change tax percentage of an existing tax code but to create a new one. May I know what are the reason for not changing existing tax codes.

In my case existing tax code are 12 years old and we are not using them no longer, so I would like to reuse them. I think it won't create any issues as per my knowledge.

Not sure, whether the 12 year tax code is related to Sales or Purchase. If it is related to sales, let us assume, you made one billing in the current week and after that you change the tax percent in the master data and saved. Now if there any open sale orders with that tax code, then, it might lead to data inconsistency and also, you need to test in case of sales returns how system is behaving.

Coming to purchase, the same case where if you change the percent in the master data and you have lot of open POs and while doing MIGO against those open POs, this might lead to incorrect posting or system may throw an error which you need to test
