Caique,
Sorry to reply late! We are trying different things..
No! The links doesn't tell how to get Attribute Set. We need Marketing Attribute SET to be come through into BW. Not able to find data source for it. Thinking of modifying data soruce 0CRM_MKTATTR_ATTR to add Attribute SET through function module. I am not ABAP expert, but I am in communication with ABAP team here to see how we can achieve it.
Regards,
Nitin
