KI858 - Details

• 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
