• What is the cause and solution for SAP error message KE/NC004 - Realignment run &1 can only be carried out exclusively ?

  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.
  Terminate Job: If you determine that a job is stuck or needs to be terminated, you can do so from the SM37 transaction. However, be cautious with this approach, as terminating jobs can lead to data inconsistencies.
  Schedule for Later: If the realignment run is not urgent, consider scheduling it for a later time when the system is less busy or when you can ensure that no other runs are in progress.
  Consult with Colleagues: If you are in a shared environment, check with your colleagues to see if someone else is running the realignment process.
  System Logs: Review system logs for any additional information that might indicate why the realignment run cannot be executed.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as KELN (for realignment) and KOB1 (for order reports) to better understand the context of the error.
  SAP Notes: Check SAP Notes for any known issues or patches related to the realignment process. Sometimes, specific versions of SAP may have bugs that are documented in SAP Notes.
  Documentation: Review SAP documentation for the Controlling module to understand the implications of realignment runs and best practices for executing them.
  
  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.
