Right, so you’re trying to view a report in Reporting Sevices that you copied from ConfigMgr and now you’re getting this. What is wrong? The SQL-account you’re using to access the Reporting Services database simply has insufficent  rights. That’s what the message above is trying to tell us.

The error in Internet Explorer

After some trial and error I gave my Reporting Services SQL-account rights as db_datareader and smsschm_users in the ConfigMgr database (SMS_<sitecode>). See screenshot below:

After that, reports work great.
