I am running into a similar issue. I have a dashboard panel that users need access to but do not have access to the index that provides the data. I decided to save my search query as a report, and give it the permissions the users will need to see the data. I then make that report a panel in my dashboard. I also check my dashboard has the proper permissions for users to view my dashboard. I can see all the data just fine but when a user tries to see my panel, they get the error above. I verified that the users can run the report and see results from report that populates the panel. So I had a user run the report, and then save it to a panel in my dashboard.  The user then went to check my dashboard and saw the same message. Permissions are set to global and I verified that the users role had permission to write on my dashboard. Thanks.   -Gerb ... View more
