BW-CRM Analytics

Hi gurus

I am a BW Consultant and now i am moving into BW CRM project. I need to identify the reports on Lead Analysis, Activity Analysis, Oppertunity Analysis and Account Management-Business Partner Views. As i am new to the CRM area i have no idea about what these areas actually meant for. It would be a great help if anyone can provide me some functional orientation to the above mentioned areas.

Once i am done with the identification of the reports i will be going to install the business content for the same. So please help me in this regards.

thanks in advance
