  The SAP error message /SAPAPO/PP_OPTLOG120 indicates that an optimization run in the SAP Advanced Planning and Optimization (APO) module 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 currently running an optimization job that locks the resources needed for the new job.
  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 for them to complete their job. You can check the status of the optimization run in the APO 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. You can then communicate with them to understand the situation.
  Terminate the Job: If the job is stuck or taking too long, and you have the necessary authorizations, you can terminate the job using transaction SM37 or SM12 to release the lock.
  Check for System Issues: If this issue occurs frequently, it may be worth investigating if there are underlying system performance issues or configuration settings that need to be adjusted.
  Consult Documentation: Review SAP documentation or notes related to optimization runs and locking mechanisms for any specific recommendations or best practices.
