• What is the cause and solution for SAP error message /SAPAPO/PPO_OPT068 - Optimization run &1 locked by user &2 ?

  The SAP error message /SAPAPO/PPO_OPT068 indicates that an optimization run in SAP Advanced Planning and Optimization (APO) is currently locked by another user. This typically occurs when one user is executing an optimization run, and another user attempts to start a new optimization run for the same planning object or data set.
  Cause:
  
  Concurrent Execution: Another user is already running an optimization job, which locks the optimization process for that specific planning object.
  Unfinished Job: A previous optimization run may not have completed properly, leaving the lock in place.
  System Configuration: The system may be configured to prevent multiple optimization runs on the same data set to ensure data integrity.
  
  Solution:
  
  Wait for Completion: If another user is running the optimization, wait until they finish. You can check the status of the optimization run in the system.
  Identify the Locking User: Use transaction codes like SM12 (to view locks) or SM37 (to check job status) to identify the user who is holding the lock. 
  Contact the User: If possible, contact the user who is running the optimization to see if they can complete or cancel their job.
  Release the Lock: If you determine that the lock is due to a job that has failed or is stuck, you may need to manually release the lock. This can be done by:
  
  Using transaction SM12 to delete the lock entry if it is safe to do so.
  Checking with your system administrator or basis team before taking this step to avoid data inconsistency.
  
  
  Review Job Scheduling: If this is a recurring issue, consider reviewing the scheduling of optimization runs to avoid conflicts.
  
  Related Information:
  
  Transaction Codes:
  
  SM12: To view and manage lock entries.
  SM37: To monitor background jobs and their statuses.
  
  
  Documentation: Refer to SAP Help documentation for APO and optimization runs for more detailed information on managing optimization processes.
  User Training: Ensure that users are trained on how to manage optimization runs and understand the implications of running concurrent jobs.
  
  By following these steps, you should be able to resolve the /SAPAPO/PPO_OPT068 error and manage optimization runs effectively in your SAP APO environment.
