BODS 4.1: how to pull data from mainframe using bods 4.1 and load into ECC CRM

Hello Experts,

I'm new to BODS....Could you please help to determine the approach to be followed in order to load data using BODS 4.1 from mainframe as source and SAP ECC CRM as destination?

Please provide with some documentation in case you have any or simply providing some pointers would also be of help.

Thanks.
