How to create a crystal report based on SAP R3 Tables????????????

Dear All!!!!!!!!!!!

I am new to SAP BO crystal reports.

I want to extract the data from SAP R3 tables and design the crytal report. When i tried to make a new connection;

We have lot of connection as OLAP;OLE DB and etc, I am not sure how to establish a connection between R3 tables and crystal reports. I cannot able to find documents too...

Is there any documents available to make the connection or can anyone help me out to figure this..........

Thanks in advance.
