An Idoc adapter allows you to process SAP's IDocs in the XI Integration Engine.
iDocs of version 3.1x and higher are supported.

Don't make use of XI to communicate between SAP systems if there is a current IDoc scenario that will fulfill your needs. The XML overhead is not worth it. If you need to map an IDoc to a different format, such as XML or flat file then XI is a good choice.

The Idoc adapter is part of the Integration Server. It comprises 2 parts:

1. inbound channel - called before the pipeline
2. outbound channel - is part of the pipeline

A pipeline refers to all steps that are performed during the processing of an XML message.
The IDoc adapter converts IDocs to IDoc XML format so that they can be processed by the pipeline.

T-Codes related to the IDoc adapter:

• Maintain ports in the IDoc adapter (IDX1)
• Load, display, and delete metadata (IDX2)
• Display IDoc XML messages (IDX5)
• Configure Ack requests (SE38 - IDX_NOALE)
• Sending Acknowledgment IDocs as XI Request Messages (SE38 - IDX_ALEREQUEST)
