Hi,
Did anyone find a solution for this?
We are facing exactly the same issue.
We have Schema 1 for Incidents & Problems and Schema 2 for Change. When a request for change is created as a follow-up from an incident then this warning message is displayed - " Schema XXX, category XXX is not a valid assignment".
The incident transaction type is not added in the application area of Schema 2 and change type is not added in the application area of Schema 1. Also, in the copying control for follow-up documents 'category' hasn't been checked.
Please suggest if it can solved using the standard available settings rather than development.
Regards
Shubhra
