business component

Hi Everyone,

I am new to SAP PI and was practicng some scenarios. I got a doubt while using Business component.

For business system, we ll configure details in SLD whereas business component  is an abstract unit.Then,how the created business component points to the existing  real physical device as we dont have any IP or hostname.How the scenario will work??

Plz help me with this.

Thanks & Regards
