Hey Niranjan. An idea already exists regarding audit reporting. I recommend you add your comments to that idea about platform auditing and also add your vote to raise the ideas popularity.
Our upcoming Build 233 will include a new reporting feature that will enable this kind of reporting. You can read more about the new feature here:
The feature will be fully documented in the Build 233 release notes.

I would like to know identifying the changes and its impact of it on IB repository.
For example, I have created a platform connection and imported few reports based out of this platform. After few days I don't need this connection so I've planned to delete. But before proceeding to this, How can I get a list of dependent objects/reports without much of manual intervention out of this platform?
