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 using SAP tasks. The agents who are responsible for these tasks and have the relevant authorizations are defined in the IDoc Interface.
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 follow-on system confirms the processing status of outbound IDocs to your SAP System.
Control records and data records are exchanged in the inbound processing and outbound processing data flows. Status records are sent in the status processing data flow (exception: status confirmation using the specific SYSTAT01 IDoc type).
For more information see:
Exception handling functions are implemented when errors occur.
This section describes how the agents responsible for a work item are determined in the IDoc Interface.
Additional customizing settings may be required.
