In fact, if the service is already exposed in the bus, you do not need to create a SOAP configuration.
This inner service is expected to have a WSDL, that you reference in your BPEL. Only the BPEL SU is required.

If one of the orchestrated service is outisde the bus, and is a web service, then you need to create a SOAP provides to expose this service inside the bus.
And only then, you will be able to call this service in your BPEL.

Eventually, if you want to expose your BPEL process as a web service, outside the bus, then you need to create a SOAP consume to expose your BPEL as an external service (so that you can call it from outisde the bus).
