KE/NC004 - Details

• The SAP error message KE/NC004 indicates that a realignment run in the Controlling (CO) module cannot be executed because it is already being processed or has been scheduled to run exclusively. This typically occurs in the context of the realignment of cost centers, internal orders, or other controlling objects.
  
  Cause:
  
  Concurrent Execution: The realignment run is already in progress or has been scheduled to run by another user or process.
  Locking Mechanism: SAP uses a locking mechanism to prevent multiple users from executing the same process simultaneously, which can lead to data inconsistencies.
  System Configuration: The system may be configured to allow only exclusive runs for certain processes, which can lead to this error if another run is attempted.
  
  
  Solution:
  
  Check Running Jobs: Use transaction code SM37 to check for any running or scheduled jobs related to the realignment process. If you find an active job, you may need to wait for it to complete.
