I can create data sources that connect to SQL Analysis Servier 2012 instances, but not to the PowerPivot instance.

I followed the instructions here: http://technet.microsoft.com/en-us/library/ff191197.aspx

I used a connection string like this:

PROVIDER=MSOLAP;DATA SOURCE=http://contoso/Documents/PowerPivot_Sample.xlsx

I get the following error after trying to select a cube from the drop down: An error occurred connecting to this data source

The Event viewer gives the following error:

The Unattended Service Account "mydomain\myuser" does not have access to the server specified by the data source connection string.

Data source location: http://spdev2013-3/sites/testbicenter/Data Connections/19_.000
Data source name: New Data Source 10

Exception details:
Microsoft.AnalysisServices.AdomdClient.AdomdConnectionException: A connection cannot be made. Ensure that the server is running. ---> System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.AnalysisServices.SharePoint.Integration, Version=, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies.

Following the instructions here I installed:

  1. Microsoft® SQL Server® 2012 ADOMD.NET and Microsoft® Analysis Services OLE DB Provider for Microsoft® SQL Server® 2012 from the Microsoft® SQL Server® 2012 Feature Pack on the WFE and the server running the PPS Service
  2. Microsoft® SQL Server® 2008 R2 ADOMD.NET and Microsoft® Analysis Services OLE DB Provider for Microsoft® SQL Server® 2008 R2 from the Microsoft® SQL Server® 2008 R2 Feature Pack on the WFE and the server running the PPS Service

More info on why these steps are required is available here. Also because of a suggestion on this page I installed SQL Server 2008 R2 SP1 to update the components

I also tried to redeploy the PowerPivot farm solution.

I also verified the PowerPivot installation according to these instructions and I can view Excel spreadsheets that use PowerPivot in Excel Services, so I think that means it is working correctly.

On the server hosting the SSAS instance install the desktop experience. When accessing workbooks as a data source from SharePoint, it will connect via WebDav. WebDav is not available on the server by default and is included when you install the desktop experience feature.

  • Thanks I tried this but I'm still getting the same exception.
