  The SAP error message FKJO126 indicates that there is already a job running for a specific container ID, which is causing a conflict when trying to schedule a new job. This error typically occurs in the context of job scheduling in SAP, particularly when dealing with background jobs or batch processing.
  Cause:
  The error is triggered when you attempt to create or schedule a new job for a container ID that is already associated with an existing job that is currently running or scheduled. The parameters in the error message provide specific details:
  
  &1: Container ID
  &2: Job type or name
  &3: Run date
  &4: Run instance
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Jobs: Use transaction codes like SM37 (Job Monitoring) to check for existing jobs that are currently running or scheduled for the same container ID. Look for jobs with the same run date and instance.
  
  
  Wait for Completion: If the existing job is still running, you may need to wait for it to complete before scheduling a new job for the same container ID.
  
  
  Cancel or Delete Existing Job: If the existing job is stuck or you no longer need it, you can cancel or delete it from the job monitoring screen (SM37). Be cautious with this step, as it may affect ongoing processes.
  
  
  Change Job Parameters: If you need to run a new job immediately, consider changing the parameters (like the container ID or run date) to avoid the conflict.
  
  
  Review Job Scheduling Logic: If this error occurs frequently, review the logic in your job scheduling process to ensure that jobs are not being scheduled simultaneously for the same container ID.
