Hi Rashid,
You are not able to see the service interfaces under BS name or while doing an F4 while making other objects in ID ?
you created BS and assuming this you created for ECC then in that case unlike other BC you wont be able to add the service interface names manually or in other words when you create any object and choose communication component as your BS(in question here) then when you do an F4 then you wont be able to see the service interface.
Just try to manually type the service interface name and associated namespace and create the object in integration builder .It will work definetly.for ex: if you create an interface determination and you manually type in SI names , it will automatically populate the mapping name from ESR.
