Integration Engine
Purpose
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.
For more information about configuring the individual adapters, see:
● Configuring the IDoc Adapter
With the IDoc adapter the Integration Engine can process IDocs (Intermediate Documents).
● Configuring the HTTP Adapter
With the RFC adapter the Integration Engine can process RFCs (Remote Function Calls).
With the XI adapter the Integration Engine can be connected with other Integration Engines (using the XI 3.0 protocol).
● Configuring the Channel with Adapter Type WS
With a WS channel the Integration Engine can be connected with Web service providers or Web service consumers.
Using IDoc and RFC adapters is available for applications that have already defined IDocs or RFCs, as well as for applications of SAP components that do not yet have access to the proxy generation functions.
Integration
The Integration Engine is a runtime environment of SAP NetWeaver Process Integration (PI). The processes involved can take place between heterogeneous system components within a company, as well as between business partners outside company boundaries.
Features
As a PI runtime component, the Integration Engine has the task of receiving, processing and forwarding XML messages. During message processing, the sender agreements and receiver agreements are evaluated, the receiver is determined, and the 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. Event-Driven Message Processing, Prioritized Message Processing and Message Packaging are all possible.
