I have a problem with a report containing a subreport not running successfully when deployed to the Report Server.
The report runs successfully every time in the VS Development environment, so parameters are all setup correctly and the result is as expected accross the whole report.
No errors or warnings are listed when building or deploying.
the subreport is in the same project as the main report and deployed to the same folder in Report Manager. the individual subreport runs successfully in VS Studio (Preview Tab) and in the Report Manager portal.
the main report runs but shows the error "Subreport could not be shown" for the subreport.
Running SQL 2008 R2 Please advise.
