IC Web Client ,(CRM 7.0) creation of Tech Master Data for IS Utilities

Hi Experts,

We have created & assigne d (UTIL_IC_REG) Business Role in our project.

When I check the Technical Data option , it allows me to create ( Connection Object ,Premise & POD )

My question is how these objects are created.

Is these object first created in CRM & then replicated to ISU or it directly creates in ISU & then replicated to CRM.

Our requirement is to create Tech Master data in ISU & then replicate to CRM for Conn Object & POD.

Can anyone please guide me in this scenario
