Hello, we have reports running using SharePoint integration mode...everything was woring fine since yesterday, all of sudden started getting error while opening the reports - "The permissions granted to user are insufficient for performing this operation. ---> Microsoft.ReportingServices.Diagnostics.Utilities.AccessDeniedException: The permissions granted to user are insufficient for performing this operation."while opening the reports from SharePoint site. Please let me know if you have faced this before...we are having problem in production environment... Thanks, Gaurav
