OB52 - Not modifiable in QA system

You have the possibility to do changes when you access OB52 in Production system.
But when you access transaction OB52 in the QA system you receive this message:
Client 100 has status 'not modifiable'

Reason: In SCC4 the Client Role for this client in QA system is set to "Test". If you change it into "Production" you will have possibility to do changes in OB52 (S_ALR_87003642). Remember to change it back when you are finished.

Another solution is described in note 214132. But this solution was no good for me.
