Changing the country code in proudctive company code

Hi Folks,

My client requirement is changing the country code for one of the productive company code.

The requirement is like for xxxx company code, change Country code from IT to NL (Netherlands). Please note that already transaction data exists in the production system for this company code.

I just wanted to understand the various implications if we change the country code for a productive company code.

Your responses are highly appreciated and rewarded. Thanks in advance.

Thanks

Shankar.
