Configuring the Integration Engine for Message
Processing

You only need the following procedures in scenarios where messages are processed by the Integration Engine. These settings are not required for direct connections.
The Integration Engine enables you to process XML messages exchanged between applications in heterogeneous system landscapes. Both applications of SAP components and external applications can communicate with the Integration Engine.
As a runtime
component, the Integration Engine has the task of receiving, processing and
forwarding XML messages. During message processing,
collaboration
agreements are evaluated, the
receivers are
determined, and
mapping activities
are executed.
The individual
processing steps are called pipeline services and are defined in pipelines. It is
the task of the Integration Engine to process these pipelines correctly and
consistently. To guarantee this, you must configure the
Integration Engine accordingly and
monitor the
message processing. Both event-driven message
processing and prioritized message
processing are possible.
