RE: Customer Posting Group Codes Changed when invoiced
Dear Allen C ,
This is not a NAV error , Definitely this error regarding someone has done this or if you import anything to customer card(automated customer creation)
Check list....
1. If you having any automated customer creation - check whether the importing data might be wrong
2. Check your users who having customer card modification access and customer posting group setup Entry,Modify
3. It is possible to if some one change or modify your "customer posting groups" on system
Further cause if you worrying about it check the change log entries , who access/ modify Customer card and customer posting group
