I couldn't find the view related to SQLTaskStatus table so I've created the custom report with the above mentioned table rather than view.

This post is a continuation of my old post how to find out the status of Predefined Maintenance Tasks.

One problem could be :-

Go to Manage option of the report. Click on Manage –> Data Sources –> Click on A Shared Data Source and browse to connect to /ConfigMgr_SiteCode/{5C6358F2-4BB6-4a1b-A16E-8D96795D8602} and APPLY. Run the report. It may work.

Another problem could be with permission. Probably, you don’t have access on tables. Can you try running the following query from SQL management studio.
select * from SQLTaskStatus
