• What is the cause and solution for SAP error message /SCMTMS/PLN_BGD011 - Optimizer not called; locked objects exist ?

  The SAP error message /SCMTMS/PLN_BGD011 indicates that the optimizer could not be executed because there are locked objects in the system. This typically occurs in the context of SAP Transportation Management (TM) when trying to perform planning activities, such as route optimization or shipment planning.
  Cause:
  The error is caused by the presence of locked objects in the database that prevent the optimizer from accessing the necessary data. Locked objects can occur due to various reasons, including:
  
  Another user or process is currently accessing or modifying the same data.
  A previous transaction did not complete successfully, leaving locks in place.
  Long-running processes that hold locks on the required objects.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check for Locks:
  
  Use transaction code SM12 to check for locked entries in the system. You can filter by user or object type to identify the locks that are causing the issue.
  
  
  
  Release Locks:
  
  If you identify locks that are no longer needed (e.g., from a user session that has ended), you can manually delete those locks. Be cautious when doing this, as it may affect other users or processes.
  
  
  
  Identify the Process:
  
  Determine which process or user is holding the lock. If it is a legitimate process, you may need to wait for it to complete before attempting to run the optimizer again.
  
  
  
  Check for Long-Running Transactions:
  
  Investigate any long-running transactions that may be holding locks. You can use transaction SM66 to monitor active processes in the system.
  
  
  
  Restart the Planning Process:
  
  After resolving the locks, try to rerun the planning process that triggered the error.
  
  
  
  System Restart (if necessary):
  
  In extreme cases, if locks cannot be released and are causing significant issues, a system restart may be required. This should be done with caution and typically as a last resort.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SM12: To view and manage lock entries.
  SM66: To monitor active processes in the system.
  SM21: To check system logs for any related errors or warnings.
  
  
  
  Documentation:
  
  Refer to SAP Help documentation for more details on transportation management and the optimizer's functionality.
  
  
  
  SAP Notes:
  
  Check for any relevant SAP Notes that may address specific issues related to the optimizer and locking mechanisms.
  
  
  
  By following these steps, you should be able to resolve the /SCMTMS/PLN_BGD011 error and successfully run the optimizer in SAP Transportation Management.
