Failed external service interaction

This scenario consists of a failed payment, using message set format MT103.

In this scenario we show a failing interaction with an external service (Service 1). Then, as can be verified in the diagram, ODM is contacted again in order to receive instruction about how to deal with a failing service interaction. The Routing Slip received from this interaction contain instruction to invoke another service, Service 4. Service 4 is the service invoked in case of a failure.
