SOAP Lookups in PI 7.30 Single Stack.

Hi,

I am creating a scenario from HTTP to File . In between Message Mapping has SOAP Lookup .

But While I executing the Sceanrio, I am facing some error .

Now While reading lots of Blogs over Internet , Some of them pointed towards Creating a Dummy ICO (mandatory in  PI 7.30 ) for SOAP Lookup.

So Now my Question  are :

1. Why are we creating this Dummy ICO ?? what is the purpose ??

2. How do we create it ?? - Need to know abt Sender Service Interface , Sender Communication channel , Receiver Service Interface ??? What would be these values while creating a Dummy ICO ???

Regards
