Diagnosis
The characteristic that you want to include in the authorization isactive, but it is not marked as authorization relevant and thus shouldnot be included in the authorization.
This happens for example, when you created the authorization in anothersystem, transported it, and now want to use it in the target systemwithout having marked the associated characteristics as authorizationrelevant.
Only when intervals or hierarchy authorizations have been created, forexample with transport or generation, does the characteristic stillexist in the authorization. If you have just inserted it, you cannotsave it. On the one hand, this should prevent characteristics that arenot authorization relevant from being inserted and on the other hand, itshould help eliminate transport and generation inconsistencies.

Procedure
