• What is the cause and solution for SAP error message KI858 - Table &2 is locked by user &1 ?

  The SAP error message KI858 indicates that a specific table (denoted as &2) is locked by a user (denoted as &1). This typically occurs when a user is currently accessing or modifying data in that table, preventing other users from making changes until the lock is released.
  Cause:
  
  User Lock: A user is currently editing or has an open session that is locking the table.
  Long-running Transactions: A transaction that takes a long time to complete may hold a lock on the table.
  Uncommitted Changes: If a user has made changes but has not yet committed or rolled back the transaction, the lock will persist.
  System Errors: Sometimes, system errors or crashes can leave a lock in place.
  
  Solution:
  
  Identify the User: Determine which user is holding the lock. You can use transaction codes like SM12 (for lock entries) to view the locks and identify the user.
  Contact the User: If possible, contact the user holding the lock to see if they can complete their transaction or release the lock.
  Release the Lock: If the user is unavailable or the session is no longer active, an administrator can manually release the lock using transaction SM12. However, this should be done with caution to avoid data inconsistency.
  Check for Long-running Transactions: Use transaction SM66 (global work process overview) to check for long-running transactions that may be holding locks.
  Review System Logs: Check system logs for any errors or issues that may have caused the lock to persist.
  
  Related Information:
  
  Lock Management: Understanding how SAP handles locks is crucial. Locks are used to maintain data integrity during concurrent access.
  Transaction Codes:
  
  SM12: Display and manage lock entries.
  SM66: Monitor global work processes.
  SM21: Check system logs for errors.
  
  
  Best Practices: Encourage users to commit or rollback transactions promptly to avoid unnecessary locks. Regularly monitor and manage locks in the system.
  
  If the issue persists or if you are unsure about releasing locks, it is advisable to consult with your SAP Basis team or system administrator for further assistance.
