Question

I use SQL Server 2012 SP1 U8 and SharePoint 2013.

I confiugure Excel Service and Performance Point Service and PowerPivot Service and ...

I create an Excel File that fetch data from DataWare House in PowerPivot report.

I load this file in Documents in my Share Point Web Site.

When I click on my excel file in SharePoint, I get this Error :

'EntityDataSource'. Verify that the connection information is correct 
and that you have   permissions to access the data source.
