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.

Using adapters, the Integration Engine can also process IDocs (Intermediate Documents) and RFCs (Remote Function Calls). This option 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 integration 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, 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. Event-Driven Message Processing, Prioritized Message Processing and Message Packaging are all possible.
