Concept
Uniform processing of XML messages
The Integration Engine is used to process XML messages in the same way, regardless of how they were created.
When an XML message is processed by the Integration Engine, routing information is evaluated, at runtime the physical receiver systems are determined, and mappings are executed.
XML messages do not have to be processed in a single SAP system. Depending on both the type of message and the application data it contains, the XML message may have to be forwarded to other SAP systems. While the message is being processed, routing information is evaluated, the physical receiver systems are determined at runtime, and mapping activities are executed.
Pipelines
The steps to be performed during the processing of an XML message are defined in pipelines. Pipelines are identified by a pipeline ID and a logical pipeline ID. They represent a strict processing run for particular XML messages and differ according to the role of the Integration Engine. The individual processing steps are called pipeline elements. The pipeline service defines the function that is called by a pipeline element.
