• What is the cause and solution for SAP error message IDOC_ADAPTER654 - Entry with the same key already exists ?

  The SAP error message IDOC_ADAPTER654, which states "Entry with the same key already exists," typically occurs in the context of IDoc processing when there is an attempt to create or update an IDoc that has a duplicate key in the target system. This can happen in various scenarios, such as during data imports or when processing IDocs that are meant to update existing records.
  Causes:
  
  
  Duplicate IDoc Processing: The IDoc being processed has a key that already exists in the target database. This can happen if the same IDoc is sent multiple times or if there is a retry mechanism that resends the IDoc without proper handling of existing records.
  
  
  Incorrect Mapping: The mapping of fields in the IDoc to the target system may not be set up correctly, leading to conflicts in key values.
  
  
  Data Integrity Issues: There may be issues with the data being sent, such as incorrect or duplicate entries in the source system.
  
  
  Concurrency Issues: If multiple processes are trying to create or update the same record simultaneously, it can lead to this error.
  
  
  Solutions:
  
  
  Check for Duplicates: Before sending IDocs, ensure that there are no duplicate entries in the source system. You can implement checks to prevent sending duplicate IDocs.
  
  
  Review IDoc Processing Logic: Ensure that the logic for processing IDocs in the target system is correctly handling existing records. This may involve updating existing records instead of trying to create new ones.
  
  
  Error Handling: Implement error handling mechanisms to manage retries and avoid sending the same IDoc multiple times without resolving the underlying issue.
  
  
  Data Validation: Validate the data being sent in the IDoc to ensure that it conforms to the expected format and does not contain duplicates.
  
  
  Use Unique Identifiers: If applicable, use unique identifiers for records to prevent conflicts when processing IDocs.
  
  
  Consult Logs: Check the application logs and IDoc monitoring tools in SAP (such as WE02 or WE05) to get more details about the specific IDoc causing the error and the context in which it occurred.
  
  
  Related Information:
  
  IDoc Monitoring: Use transaction codes like WE02 or WE05 to monitor IDocs and identify issues related to specific IDocs.
  SAP Notes: Check for relevant SAP Notes that may address this specific error or provide additional guidance on handling IDoc processing issues.
  IDoc Configuration: Review the configuration settings for IDoc processing in your SAP system, including message types, partner profiles, and port settings.
  
  By addressing the root cause of the duplicate key issue and implementing proper validation and error handling, you can resolve the IDOC_ADAPTER654 error effectively.
