Pipelines and Pipeline Services
Definition
Pipeline is the term used to refer to all steps that are performed during the processing of an XML message. The individual processing steps are called pipeline elements. Pipeline services provide functions for the processing of XML messages and are represented by the individual pipeline elements. Each pipeline element is linked to a pipeline service. Pipeline services can be used by more than one pipeline element.Use
Pipelines represent a fixed processing run for particular XML messages and differentiate themselves depending on the role of the
Integration Engine. There are pipelines for a local Integration Engine in the sender or receiver system, or for a central Integration Engine that is configured as the Integration Server, for example.Structure
A pipeline comprises individual pipeline elements that an XML message must perform when it is processed. Each pipeline element calls a pipeline service.
Pipeline services read and change inbound XML messages, like for example,
mapping or routing. They can also call processing processes, for example functions to create business data in an SAP component. The service type, number, and sequence are specified for each pipeline and cannot be changed.Integration
The pipeline services to be used are either part of the Integration Engine itself or originate from other areas of the
SAP Exchange Infrastructure. You call pipeline services from one standard interface.
