  Cause:
  
  Duplicate IDoc Transmission: The most common cause of this error is that the same IDoc has been sent multiple times from the sending system. This can happen due to network issues, retries in the sending system, or incorrect configurations.
  IDoc Processing Logic: The IDoc processing logic in the receiving system may not be set up to handle duplicates properly, leading to this error when it encounters an IDoc that has already been processed.
  IDoc Numbering Issues: There may be issues with the IDoc number generation or management, causing the system to think that an IDoc with the same number has already been processed.
  
  Solution:
  
  Check IDoc Status: Use transaction WE02 or WE05 to check the status of the IDoc in question. Look for the IDoc number mentioned in the error message and see if it has already been processed successfully or if it is still in a processing state.
  Identify Duplicate Source: Investigate the source system to determine why the IDoc was sent multiple times. This may involve checking logs or configurations in the sending system.
  Adjust IDoc Processing Logic: If the IDoc is being sent correctly but still causing issues, you may need to adjust the IDoc processing logic in the receiving system to handle duplicates more gracefully.
  Manual Intervention: If necessary, you can manually process or delete the duplicate IDoc if it is confirmed that it should not be processed again.
  Consult Documentation: Review SAP documentation or notes related to IDoc processing in EWM for any specific configurations or known issues that might relate to your situation.
  
  Related Information:
