I have over a 1,000 possible selections for the parameter in the SSRS 2008 R2 (integrated mode) report.
One is an "all offices" option which equates in logic to the "select all" option -- works fine by the way.
Here's the issue:
- If the user selects "select all" and hits apply, no report is shown -- the "apply" button goes grey for awhile then goes back to black, but no report is shown
- If the user selects a few offices and hits apply, the report is shown
What appears to be going on is that SSRS cannot handle passing a multi-valued parameter if that parameter contains a very high number of selections/items.
One workaround is to go to a cascading filter/parameter, but if anyone has also seen this SSRS problem with a large number of multivalue selections I'd be interested in your experience/workarounds. Thanks, comments welcome.
