• What is the cause and solution for SAP error message KE/NC003 - Realignment run &1 is already locked by user &2 ?

  The SAP error message KE/NC003 indicates that a realignment run is already locked by another user. This typically occurs in the context of the Controlling (CO) module, specifically when dealing with realignment processes in Profit Center Accounting or Cost Center Accounting.
  Cause:
  The error is caused by the following scenarios:
  
  Concurrent Access: Another user is currently executing a realignment run, which locks the process to prevent data inconsistencies.
  Unfinished Process: A previous realignment run may not have been completed or was interrupted, leaving the process in a locked state.
  User Lock: The system has a mechanism to prevent multiple users from running the same process simultaneously, which is a standard practice to ensure data integrity.
  
  Solution:
  To resolve the KE/NC003 error, you can take the following steps:
  
  
  Check Active Sessions:
  
  Identify if another user is currently running the realignment process. You can do this by checking the transaction logs or using transaction codes like SM66 (Global Work Process Overview) or SM12 (Display and Delete Locks).
  If you find that another user is running the process, you may need to wait until they complete their run.
  
  
  
  Terminate the Lock:
  
  If you determine that the lock is due to an unfinished process (e.g., a user has left the session open), you can use transaction SM12 to delete the lock entry. However, be cautious with this approach, as it may lead to data inconsistencies if the other user is indeed processing data.
  
  
  
  Communicate with Users:
  
  If you are in a multi-user environment, communicate with your team to ensure that no one else is running the realignment process at the same time.
  
  
  
  Retry the Process:
  
  Once the lock is resolved, you can retry the realignment run.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  KE30: For Profit Center Report
  KE37: For Realignment
  SM12: To manage locks
  SM66: To view active processes
  
  
  Documentation: Refer to SAP Help documentation for detailed information on realignment processes and locking mechanisms in the CO module.
  User Roles: Ensure that users have the appropriate roles and permissions to execute realignment runs to avoid unnecessary locks.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis team or SAP support for further assistance.
