I've installed SQL Server 2012 SP1 + SP server 2012 + SSRS and PowerPivot add-in.
I also configured excel services correctly. Everything works fine but the powerview doesn't work!
While I open an excel workbook consist of a PowerView report an error occurs:"An error occurred while loading the model for the item or data source 'EntityDataSource'. Verify that the connection information is correct and that you have permissions to access the data source."
error detail:

Please help me to solve this issue. I don't know if uploading the excel workbook is enough or maybe It needed to connect to another data source.
I Appreciate in advance.
