Question

I have configured TFS 2010, but when I try to load the project dashboard for a team project, it returns a reporting service error so I am not able to see the "Task Burndown (hours)" and " Burn Rate (hours/day)". Other parts of the page are working fine.

The error is as:

An error has occurred during report processing. (rsProcessingAborted) Get Online Help
Cannot impersonate user for data source ‘TfsReportDS’. (rsErrorImpersonatingUser) Get Online Help
Log on failed. (rsLogonFailed) Get Online Help
For more information about this error navigate to the report server on the local server machine, or enable remote errors

Answer 1

I got resolution finally….

Go to analysis service.

    You will see database named as TFS_Analysis.
    Go to Roles node.
    View properties of "TfsWarehouseDataReader".
    Click on Data Sources.
    Now you will see Tfs_AnalysisDataSource.
    Change access to "Read" and check "Read Definition" box. Now Click OK and You are Done.
