Configure Excel Services 2010 for data refresh « Howard @ MSFT selling BI. October 2010. PowerPivot Workbook has 2 kinds of data sources, one is from its Pivot table cache, and the other is from PowerPivot Analysis Cubs.
Then what about Data Refresh? PowerPivot Data Refresh is to refresh Analysis Cubs from external data sources, and as part of this refresh process, the workbook is updated as well. The credential used for data refresh can be: Unattended account, embedded window credential, or SSS Notice, there is no window authentication listed above, which means the logon user credential is never used for data refresh. So obviously data in Analysis Service is not security trimmed.

After all, as you can see in Denny’s post, you can see the workbook and you even have a thumbnail for it in the Gallery. What’s up here?
