Does anyone know how to kick off a service on another IS from TN?

From the Processing Rules/Action/Execute a Service I want to be able to execute a service which is on a different IS. Is this possible or am I not understanding how TN works?

If this is possible, can someone point me in the right direction?

Thanks,
Victor

Victor,
To handle this TN it is not possible,but another option kickoff some service on the same IS and build a logic in the flow using remote invoke the service on different IS.

But using TN processingrule ExecuteAService(invoking which is on another IS)is not doable.
