CUSTOMER_MAIN or BUPA_MAIN

Hello Gurus,

I have a doubt with an adapter object in CRM 7,0. I need to transfer business partners from CRM to R3.

But I am not sure what is the correct object to run in order to send the BPs to R3.

What is the correct adapter to send my BPs to R3: CUSTOMER_MAIN OR BUPA_MAIN?

Any suggestion?

Thanks 4 all.
