Need information/training material regarding SAP CRM Functional

Hello,

I am a SD Consultant.

I want to learn SAP CRM (Functional) on my own without going to any training institute or some thing.

Therefore, can anyone help me in forwarding the link(s) or document(s) with which I can learn about SAP CRM (Functional).

I want information/training material regarding SAP CRM 7.0 (on system/software working, not the general information, for example- why CRM, where CRM, etc)

For example, about org data, org structure, possible scenarios, etc.

Thanks in advance for spending your valuable time for me.

Regards,

T. Chaitanya
