The IDoc adapter is used by SAP systems to connect to a centrally configured Integration Engine using IDocs. A system that has an Integration Engine of this type is referred to as the Integration Server. External systems can also use the IDoc adapter to connect to an Integration Server.
Implementation Considerations
Only use the IDoc adapter to integrate SAP systems with the Integration Server if a scenario of this kind suits your requirements. For example, if you want to make IDoc data in the form of XML messages available to additional receivers, or if you want to integrate different components or integration processes that were previously not integrated. Only stop using existing functioning IDoc scenarios after serious consideration.Integration
The IDoc adapter is part of the Integration Server. Essentially, the IDoc adapter comprises two parts, namely an adapter at the Integration Server inbound channel, and an adapter at the Integration Server outbound channel. The metadata for the IDoc types involved is shared.The adapter at the inbound channel is located before the Integration Server pipeline and calls this pipeline. The adapter at the outbound channel, however, is called by the pipeline, and can therefore be regarded as part of the pipeline.
The connected systems transfer or receive IDocs through their IDoc RFC interface.
