CRM and SD Partner Functions

Hi Friends,

We are trying to extact Partner Functions from both of our R3-SD and CRM 5.0 systems, to NW2004s.

In R3-SD, you can name several business partner functions on the SD Contract. Also, in CRM you can name several business partner functions on the Sales Opportunity.

So, we need to extract all of the Business Partner Functions per Opportunity (CRM), and per Contract (R3-SD) to BW.

Has anyone done this? Is there a delivered extractor? How about configuration in the CRM and R3-SD environments for this?

Thanks in advance for your help!
