IDoc Error Processing 

TCP/IP Errors

The basis for IDoc transmission between systems is TCP/IP. If an error occurs during the transfer, the connection between the sending system and the receiving system is interrupted.

Based on return codes in the RFC function used, you can see in the sending system whether an RFC call has worked. If there are TCP/IP errors, break the connection and send the IDoc again.

Technical Errors

If errors occur in the ALE service layer during sending or receiving of IDocs, then there is a technical error.

If a technical error occurs, Extended Warehouse Management (EWM) sends a workflow work item for each incorrect IDoc in the form of an error message. The system sends this message to all responsible users. Based on the error message, the user can analyze the error and post the document subsequently. For more information, see Processing Technical IDoc Errors.

Logical Errors

The system saves a received IDoc in the database before the IDoc has actually been processed. The system breaks off communication with the external system before the transferred data is then processed.

If an error occurs during processing of an IDoc in the application system (EWM), then there is a logical error. In this case, EWM creates a workflow work item for each incorrect IDoc.
