Create a PowerPivot data connection (PerformancePoint Services)
Applies to: SharePoint Server 2010 Enterprise
PerformancePoint Services in SharePoint Server 2010 supports PowerPivot models as a data source. You can use data in a PowerPivot model and build interactive dashboards using PerformancePoint Services features such as Key Performance Indicators (KPIs), Scorecards, Analytic Charts, Analytic Grids and Filters.
PerformancePoint Services accesses external data sources by using a delegated Windows identity. Consequently, external data sources must reside within the same domain as the SharePoint Server 2010 farm. If external data sources do not reside within the same domain, authentication to the external data sources will fail. For more information, see Planning considerations for services that access external data sources.
Create a PowerPivot data source connection
To use PowerPivot as a data source within PerformancePoint Services dashboard, you must have PerformancePoint Services activated on a SharePoint Server 2010 farm and have PowerPivot for SharePoint 2010 installed. Once a PowerPivot model is created, it must be uploaded to a SharePoint Server site that has PowerPivot for SharePoint enabled.
You must apply the hotfix detailed in the Microsoft Knowledge Base article When you run a .NET Framework 2.0 based application, a System.AccessViolationException exception occurs, or a deadlock occurs on two threads in an application domain (Article ID 975954) in order to use PowerPivot as a data source in PerformancePoint Services.
You must have ADOMD 10 installed on the server on which you are authoring the Dashboard in order to access a PowerPivot workbook as a data source.
In PerformancePoint Services, the security setting for data sources is stored in each data source. By using PowerPivot as a data source, you can authenticate either using an unattended service account or a Per-user identity. Per-user identity requires Kerberos protocol.
|You cannot authenticate to a PowerPivot data source by selecting the Unattended Service Account and add authenticated user name in connection string option.|
Time Intelligence is not supported for PowerPivot data sources.
