SQL Server 2008 Reporting Services Throwing Error

Question

I am getting the following error ( which it was working fine previously )

An error has occurred during report processing. (rsProcessingAborted) The execution failed for the shared data set 'CombinedStatsPerClient'. (rsDataSetExecutionError) Cannot create a connection to data source ' Data source for shared dataset'. (rsErrorOpeningConnection) For more information about this error navigate to the report server on the local server machine, or enable remote errors

What can be the issue, Connection..or

Answer 1

The Problem was with the database connection string which is sorted

Answer 2

From reading the error:

Cannot create a connection to data source ' Data source for shared dataset'.

Sounds like there is something wrong with either your connection, or the connection you have set up for your report.
