  System Configuration: There may be configuration settings that allow multiple instances to run, but they are not set up correctly.
  
  
  Solution:
  
  
  Check Running Processes: 
  
  Use transaction codes like SM37 to check for any active jobs related to the preselection scheduler. If you find a job that is still running, you may need to wait for it to complete.
