My client had customers created under account group 0001 sold to
Then they created a copy of account group called Y001 sold to (for a new sales org and co code)
Now they want to extend all customers created under 0001 Sold to --> to Y001 sold to (and new sales area . co code)
But when the customers are extended, under Y001 , upon saving the system changes account group Y001 to 0001 again
Is there a way the account group can be changed from 0001 to Y001, while extending customer master ?
Any help would be appreciated
Thanks in advance
