Dear Friends
I have created an analysis which has a PIE Chart as the output and appears as below. It is the summary of products across 3 subject area. I have created the hierarchy necessary to drill down and it works fine when I consider single Subject Area.
Since, I have combined data from 3 subject area, the drill down functionality has been disabled. By any means, can we bring the Drill Down functionality in this case.

Thanks in advance.
Regards
Prasanna
