Fix: PowerPivot for SharePoint Data Refresh



  1. On the Analysis Services Server running in SharePoint mode, Add the Analysis Services service account to the “Act as part of the operating system” privilege:
    1. Run “secpol.msc”
    2. Click Local Security Policy, then click Local policies, and then click User rights assignment.
    3. Add the service account.
  2. Restart Excel Services and reboot the Analysis Services server.

Delegation from the Excel Services service account or from Claims to Windows token service (C2WTS) to the Analysis services instance is not required. Therefore no configuration for KCD from Excel Services or C2WTS to PowerPivot AS service is necessary. Note: If the backend data source is on the same server as the Analysis Services instance, delegation is not required.
