Creating Report Datasets from a Microsoft SharePoint List
To include data from a Microsoft SharePoint list in your report, you must add or create a dataset that is based on a report data source of type Microsoft SharePoint List. This is a built-in data source type based on the Microsoft SQL Server Reporting Services SharePoint List data extension. Use this data source type to connect to and retrieve list data from SharePoint Foundation 2010, SharePoint Server 2010, Windows SharePoint Services 3.0, and Office SharePoint Server 2007 sites.
For more information, see Getting Data from a SharePoint List Data Source Type (Report Builder 3.0) in the Report Builder 3.0 documentation on msdn.microsoft.com.
