Cannot generate reports from SQL Management Data Warehouse I'm running SQL Server 2008 R2 and have installed the MDW on one server and have a Data Collector collecting and uploading the server activity, query results, and Disk activity data to the MDW. When I select any of the reports from the MDW with Data Collection > Reports > Management Data Warehouse I receive the error:


  Exception has been thrown by the target of an invocation - > Object reference not set to an instance of an object.


This occurs for all 3 reports and after I've waiting some time and data has been uploaded from the data collector. I do not have SSRS running, but read that isn't necessary.

Any suggestions?
Just ran into and resolved this issue today.  Select the View Logs context menu option in the Data Collection Sets--the data upload could have failed, which causes the reports to generate this issue.
