Add MSOLAP.5 as a Trusted Data Provider in Excel Services
Applies To: SQL Server 2016
MSOLAP.5 refers to the Analysis Services OLE DB provider for SQL Server 2012. Excel Services must trust this provider before it will make the connection request that results in the availability of Power Pivot data on a server.
If you configured Power Pivot for SharePoint using the Power Pivot Configuration Tool, MSOLAP.5 might already be a trusted provider because the tool includes an action that satisfies this requirement. However, if you are using PowerShell, Central Administration, or if you excluded the trusted provider action in the configuration tool, the provider might be missing, which case you should add it now as part of configuring the farm for Power Pivot data access.
You only need to perform this step once for each Excel Services service application.
Each physical server that handles a Power Pivot data request, such as a Power Pivot for SharePoint server or an Excel Services server, must have the OLE DB provider installed on the computer. A Power Pivot for SharePoint installation always includes the OLE DB provider, but if Excel Services is running on a computer that does not have Power Pivot for SharePoint, you must install the provider manually. For more information, see Install the Analysis Services OLE DB Provider on SharePoint Servers.
In Central Administration, click Manage service applications, and then click the Excel Services service application.
Click Trusted Data Providers.
Verify that MSOLAP.5 appears in the list. Depending on how you configured Power Pivot for SharePoint, MSOLAP.5 might already be trusted.
If it is not listed, click Add Trusted Data Provider.
In Provider ID, type MSOLAP.5.
For Provider Type, ensure that OLE DB is selected.
In Provider Description, type Microsoft OLE DB Provider for OLAP Services 11.0.
