Processing IDocs 
Processing IDocs
Use
The business data is saved in IDoc format in the IDoc interface and is forwarded as IDocs. If an error occurs, exception handling is triggered via workflow tasks. The agents who are responsible for these tasks and have the relevant authorizations are defined in the IDoc interface.
Features
The IDoc interface supports three types of data flow with the external system:
IDocs are transferred to a receiving system from your SAP System.
IDocs are transferred to your SAP System from an upstream system.
The receiving system confirms the processing status of outbound IDocs to your SAP System.
Control records and data records are sent for IDoc inbound processing and IDoc outbound processing. Status records are sent in the status confirmation data flow (exception: status confirmation via the specific IDoc type SYSTAT01).
