How to customize the system exceptions raised in PPS Dashboard?

I have created a analytical chart and used in PPS dashboard.

But while drill down directly to the lower/last level i am getting the exception: "Unable to create report. Query produced too many results”.

Please let us know the if we have perminent fix to this?

And also let me know how to capture this exception and to show a user-friendly message to the end user?

Thanks, Sekhar.
