Change of RFC dest during Create BP via DSWP

Dear all,

I'm creating Business Partner via Tcode DSWP. Where in the screen "Create Business partner" got to know there are Satellite system being attached on the tree in left hand.

My questions:

1) may i know how can i perform the config if i want to edit/delete/add the system?

2) How can i assign the RFC dest accordingly each of the system?

Please comment.

Thanks in advance.
