  Identify the Lock: Use transaction codes like SM12 (to view and manage locks) to identify which user or process is holding the lock on the document.
  Terminate the Lock: If necessary and if you have the appropriate permissions, you can delete the lock entry in SM12. However, this should be done with caution, as it may disrupt the other user's work.
  Check for Long-running Processes: Investigate if there are any long-running processes that might be holding the lock. You can use transaction SM66 to monitor active processes.
  Review Custom Code: If the issue persists, review any custom code or enhancements that might be affecting document locking behavior.
