We migrated our MOSS 2007 site (with around 500 SSRS 2005 reports and around 20-30 data sources) to MOSS 2013 and SSRS 2012. Now when I try to click on Manage Data Sources on any of the existing report (rdl) we get error:
Report Server has encountered a SharePoint error. --->
Microsoft.ReportingServices.Diagnostics.Utilities.SharePointException: Report
Server has encountered a SharePoint error. --->
Microsoft.SharePoint.SPException: Exception from HRESULT: 0x80131904 --->
System.Runtime.InteropServices.COMException: Exception from HRESULT:
0x80131904
Also when we try edit data source definition (rsds) it gives the same above error.
We have configured SSRS 2012 as service application on MOSS 2013
Any help appreciated.
