I am adding a SQL Server Reporting Service Report Viewer Webpart onto a webpart page and i place a report generated using SSRS in the document library. I have two reports one with no parameter and one with user parameter.
The one without user parameter works fine on sharepoint webpart but when i try to add report the one with parameter to a report-viewer webpart i get the following issue
An error occurred during local report processing. An error has occurred during report processing. An attempt has been made to use an unregistered data extension, 'XML'. To use this data extension, it must be registered in the Web.config file of this Web application.
Refer the Image below.
NOTE: The DatatSource connection is of type XML as i am using webservice to fetch the data.
