  To resolve this error, you can take the following steps:
  
  
  Check for Active Processes: Verify if there is an ongoing mass LDC process. You can do this by checking the relevant transaction codes (like SM37 for job monitoring) to see if any jobs are currently running that might be causing the lock.
  
  
  Wait for Completion: If you find that a mass LDC job is running, you will need to wait for it to complete before attempting to make any changes to event details.
  
  
  Review Job Logs: If the job has failed or is taking too long, review the job logs for any errors or warnings that might indicate why it is not completing.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to mass LDC processes for any specific guidelines or best practices.
