• What is the cause and solution for SAP error message E0857 - EDI: IDoc number is not unique, IDoc not reloaded ?

  The SAP error message E0857, which states "EDI: IDoc number is not unique, IDoc not reloaded," typically occurs in the context of Electronic Data Interchange (EDI) when dealing with IDocs (Intermediate Documents). This error indicates that the system has encountered an IDoc number that is not unique, which prevents the IDoc from being processed or reloaded.
  Cause:
  
  Duplicate IDoc Numbers: The most common cause of this error is that there are multiple IDocs with the same number in the system. Each IDoc should have a unique identifier, and if the same IDoc number is found more than once, the system will not know which one to process.
  IDoc Processing Issues: If an IDoc has already been processed or is in a status that does not allow it to be reloaded, attempting to reload it can trigger this error.
  Database Issues: In some cases, database inconsistencies or issues with the IDoc processing logic can lead to duplicate entries.
  
  Solution:
  
  Check for Duplicates: Use transaction codes like WE02 or WE05 to check for IDocs with the same number. You can filter by the IDoc number to see if there are duplicates.
  Delete or Archive Duplicates: If you find duplicate IDocs, you may need to delete or archive the unnecessary ones. Be cautious with deletion; ensure that you are not removing IDocs that are still needed for processing.
  Review IDoc Status: Check the status of the IDoc in question. If it has already been processed, you may need to create a new IDoc instead of trying to reload the existing one.
  Consult Logs: Review the application logs (transaction SLG1) for any additional error messages or warnings that might provide more context about the issue.
  System Configuration: Ensure that your EDI configuration is set up correctly to prevent duplicate IDoc numbers from being generated in the first place. This may involve reviewing the settings in transaction WE20 (Partner Profiles) and WE21 (Port Definitions).
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for further assistance.
