• What is the cause and solution for SAP error message TN_PROCESS123 - Object &1 &2 is used by &3 &4 ?

  The SAP error message TN_PROCESS123 indicates that a specific object (identified by &1 and &2) is currently being used by another process (identified by &3 and &4). This typically occurs in scenarios where multiple transactions or processes are trying to access or modify the same object simultaneously, leading to a conflict.
  Cause:
  
  Concurrent Access: The object is locked by another user or process, preventing your transaction from accessing it.
  Long-running Transactions: A transaction that takes a long time to complete may hold locks on objects longer than expected.
  Incorrect Configuration: There may be issues with the configuration of the system that lead to improper locking mechanisms.
  
  Solution:
  
  Wait and Retry: If the object is locked by another user, you may need to wait until the other process completes and then try again.
  Identify the Lock: Use transaction codes like SM12 (to view locks) or SM21 (to check system logs) to identify which user or process is holding the lock on the object.
  Terminate the Lock: If necessary and if you have the appropriate permissions, you can terminate the session that is holding the lock using SM12. However, be cautious with this approach as it may lead to data inconsistencies.
  Check for Long-running Processes: Investigate if there are any long-running processes that can be optimized or terminated.
  Review Configuration: Ensure that the system configuration is set up correctly to handle concurrent access to objects.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12, SM21, SM37 (for job monitoring), and ST22 (for dumps) to troubleshoot further.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
