Uploading data into 0CRM_CO1 cube

Hi all,

i'm trying to upload data into the above said CRM cube... its a content cube .. but when i'm trying to see what is the datasource in the content i dont see any datasource.

The question is ... do i need to create a generic datasource or there is some other way. Can anyone, let me know the steps too that should be followed to get the data from R/3 to BW into this cube?

Thanks in advance,

Mav
