Hi, I have a rdl file from RS2005. I can generate the report, export it to PDF without any problem. But with the same rdl file in RS2008 and same data, when I export it to PDF. I got the following error in the ReportServerService log file. reportrendering!ReportServer_0-6!135c!08/13/2009-10:08:14:: e ERROR: Throwing Microsoft.ReportingServices.ReportProcessing.UnhandledReportRenderingException: An error occurred during rendering of the report., ;

Hello,Based on the call stack this looks like something that we fixed in a Cumulative Update for SQL Server 2008. I recommend installing 2008 SP1 and the latest cumulative updates and seeing if that resolves your issue.2008 SP1 download: http://www.microsoft.com/downloads/details.aspx?FamilyID=66ab3dbb-bf3e-4f46-9559-ccc6a4f9dc19&displaylang=enLatest SP1 cumulative updates location: http://support.microsoft.com/kb/971491/en-usBest regards,ChrisSSRS TeamThis posting is provided "AS IS" with no warranties, and confers no rights.

Hi Chris, thank you for the reply, and sorry for the delay, I will try it on Monday and let you know. Thanks
