Integrating BI reports (with drill down) in EP

Hi All,

We want to integrate some BI reports in EP. What we want to achieve is:

Display a graph (eg indicating sales revenue) in the iView

Upon user click, drill down the report to view by various criteria.

Would appreciate if anyone can provide tips on how to achieve this. Ive been contemplating on whether to use VC etc. My apologies for not being so specific as im unfamiliar in the BW arena. Thanks!
