Hello Dominik,
Some more information that may be helpful:
Work Mode scheduled on Technical System is inherited by the underlying Technical Instances. However, they are not inherited by host and database .
For host and database a separate work mode needs to be scheduled. Work Mode scheduled on Host is inherited by the underlying Technical Instances.
Work Mode scheduled on Database is not inherited by any other component.
Information on Work mode settings made during the System Monitoring setup
Regards,
Ruth
