The communication between the service consumer and service provider is either direct from one system to the other (point-to-point), or mediated (mediated communication).

In the case of mediated communication, you use SAP NetWeaver Process Integration (Integration Server) as the intermediary between the service consumer and service provider. Consequently, more integration functions are available.

This graphic is explained in the accompanying text.

  • Point-to-Point Services-Based Communication

    To execute a service of another system, the application calls a proxy in the application system directly. The result of the call is that the application system sends a request message to the service provider. The application system replies with a response message.

  • Mediated Services-Based Communication via SAP NetWeaver Process Integration (PI)

    You use the Integration Server of SAP NetWeaver Process Integration as an intermediary between the service provider and the service consumer.

    Via PI you can, for example, integrate with systems that do not provide Web services connectivity.

    You can also perform a mapping between the inbound and outbound messages.

    You can also configure point-to-point communication with Process Integration.
