• What is the cause and solution for SAP error message WL645 - Background job & for automatic restart cannot be scheduled ?

  The SAP error message WL645 indicates that a background job cannot be scheduled for automatic restart. This typically occurs when a job fails and the system is unable to set it up for a retry. Here are some common causes, solutions, and related information for this error:
  Causes:
  
  Job Configuration Issues: The job may not be configured correctly for automatic restart. This could be due to missing parameters or incorrect settings.
  Job Status: The job might be in a status that does not allow for a restart, such as "Finished" or "Canceled."
  System Resource Limitations: There may be limitations on system resources, such as memory or processing power, preventing the job from being rescheduled.
  Job Dependencies: The job may have dependencies on other jobs that have not been met, preventing it from being restarted.
  Error Handling Settings: The error handling settings for the job may not allow for automatic restarts after a failure.
  
  Solutions:
  
  Check Job Configuration: Review the job configuration in transaction SM37 (Job Monitoring) to ensure that it is set up correctly for automatic restart. Look for the "Restart" option in the job definition.
  Review Job Status: Check the status of the job. If it is not in a state that allows for a restart, you may need to manually restart it or adjust its status.
  Adjust System Resources: If resource limitations are causing the issue, consider optimizing system performance or scheduling the job during off-peak hours.
  Check Dependencies: Ensure that all dependencies for the job are met. If the job relies on other jobs, make sure those jobs have completed successfully.
  Modify Error Handling: If the job's error handling settings do not allow for automatic restarts, you may need to modify these settings to enable retries.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SM37 (Job Monitoring) and SM36 (Define Background Job) to manage and monitor background jobs.
  Job Logs: Review the job logs for any specific error messages that can provide more context on why the job failed and could not be restarted.
  SAP Notes: Check SAP Notes for any known issues or patches related to background job scheduling and automatic restarts.
  System Logs: Review system logs (transaction SM21) for any underlying issues that may be affecting job scheduling.
