no. of range for customer
Two different no. of ranges for customers are defined for two different sales organizations.
Q1: Why customers can be extended between those two sales organizations, i.e. customer 1234 can be extended to sales org. 1002 wihout changing its customer code (example below)?
Q2: Customers under different sales organizations have different reconciliation accounts. It's not proper to extend, right?
Q3: How to prevent from extending?
customer 1234 under sales org. 1001 has reconciliation account 6000000
customer ABCD under sales org. 1002 has reconciliation account 6010101
I was just thinking why you want to restrict this? I mean if you dont want to extend simply dont extend..... The authorization of creation of customer and extension will be with some specific person. So it depends on business also.
Anyways if you want to restrict then you can check with Mr Santosh's suggestion. If it wont work then you will have to put a check in Account group User exit to check the Number range and account group and then not allow the customer to extend.
