• What is the cause and solution for SAP error message S_UNIFIED_CON104 - Rejected lock object is &1. Conflict with user &2 and obj_type &3 ?

  The SAP error message S_UNIFIED_CON104 indicates a conflict with a lock object in the SAP system. This error typically occurs when a user tries to access or modify a resource that is currently locked by another user. The message provides specific details about the lock object, the user holding the lock, and the object type involved.
  Cause:
  
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. When a user accesses a resource (like a table or a transaction), a lock is placed on that resource.
  Concurrent Access: If another user tries to access the same resource while it is locked, the system will reject the request and generate this error message.
  Long-Running Transactions: If a transaction takes too long to complete, it can lead to prolonged locks, causing conflicts with other users.
  Incorrect Lock Management: Sometimes, locks may not be released properly due to programming errors or system issues.
  
  Solution:
  
  Identify the Lock: Use transaction code SM12 to view the list of active locks. You can filter by the lock object name (provided in the error message) to find the specific lock.
  Check the User: Identify the user who holds the lock (as indicated in the error message) and determine if they are still working on the transaction or if it can be safely terminated.
  Release the Lock: If the user is no longer active or if the lock is no longer needed, you can manually delete the lock entry in SM12. Be cautious when doing this, as it may lead to data inconsistencies if the user is still working on the transaction.
  Review Application Logic: If this error occurs frequently, review the application logic to ensure that locks are being managed properly. This may involve optimizing long-running transactions or ensuring that locks are released promptly after use.
  Consult Documentation: Check SAP notes or documentation related to the specific lock object for any known issues or recommendations.
  
  Related Information:
  
  Transaction Codes:
  
  SM12: Display and manage lock entries.
  SM21: System log for checking any related errors or warnings.

  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that may address specific issues related to the lock object in question.
  Performance Monitoring: Use transaction ST03N to analyze performance and identify long-running transactions that may be causing locks.
  
  By following these steps, you should be able to resolve the S_UNIFIED_CON104 error and prevent it from occurring in the future.
