1218482 - Error: "Failed to Open Report" in .NET using 'ICachedReport' interface


A Microsoft Visual Studio .NET web application uses the Crystal Reports 10 for .NET SDK as the reporting development tool. The application uses the 'ICachedReport' interface to open and cache reports. After several reports are cached, when attempting to open more reports, the following error message appears:

"Failed to Open Report".


The issue has been identified and tracked under ID ADAPT00381655.


The intent of the 'ICachedReport' interface is to share a small number of large reports (reports that take a long time to process) among a large number of users that view the report with the same data. Caching a large number of reports using the 'ICachedReport' interface is not recommended.

The following are some general guidelines for usage of the 'ICachedReport' interface:

  • Reduce the timeout value of the cached reports. More reports can be opened again after the cached reports expire.
  • Do not cache more reports than the default maximum allowed number (75) of print jobs set in the registry.
  • Do not cache a number of reports that will exceed 60% of available physical RAM on the computer.
