Extend Customer Master Data

Hi All,

I've a requirement to extend the customer master data.

Basically, here is my scenario: Currently, we have some customers existed in the system with a company code and sales org JP02.

However, for new requirement, we need to extend the existing customer to company code and sales org JP01.

How can I do this?

I tried using LSMW but I found out that different account group or distribution channel will have different screen. It's very tedious for me to do all BDC for all kind of acc grp/dist channel.

Is there any more stable way that I can use?

Hope someone can help me, it's kind of urgent. Thank.
