Caching in reporting is useful for any highly shareable resource in an application. For our reporting, Crystal Reports default caching is easy to utilize in any application. To use the caching inherent in Crystal, we invoke in .NET code the cached report. Below is an example of how to do this.

This caching should be used with highly shareable data. In other words, for reports that will be run in a similar manner with infrequent data refreshes may be a good candidate for caching. If those running the reports use similar parameters, those reports are not good candidates for caching.  

If you're running reports against real time data stores that are updated frequently between report runs, I would not consider those good candidates. That may be a good test for a later time though!
