This is caused by the SCOM Data Access account needing some additional permissions in SQL in order to control maintenance schedules via SQL Agent.  You will need to configure this just once to get it going.

In SQL Management studio – expand Security, Logins, and find the account you used for the SDK/DAS account.

Right-click the account and choose Properties.

Select User Mapping, and check the box next to the MSDB database.

Grant the following rights for the SDK/DAS account to the MSDB database:

• SQLAgentOperatorRole
• SQLAgentReaderRole
• SQLAgentUserRole

Once you apply this one-time change, the Maintenance Schedules works perfectly.
