SM59 - Biztalk Destination

Hey Guru's I hope you can help me with this.

We are trying to Configure our DEV environment to work with Biztalk 2009. Our dev environment was never configured to work with BT

Our basis team configured a Biztalk RFC Destination. Unfortunately, when selecting Extras, System Information, Target System, The host is SAPECD with system name of SAPECD and a IP of our SAP DEV box(ECD). how do I change the target so it points to our Biztalk Server.

Any help will be appreciated.
