• What is the cause and solution for SAP error message STC_TM303 - Breakpoints are only relevant for Task List Runs ?

  The SAP error message STC_TM303 indicates that breakpoints are set in a task list run, but breakpoints are only relevant for task list runs that are executed in a debugging mode. This error typically occurs when you attempt to debug a task list that is not being executed in a way that allows for breakpoints to be hit.
  Cause:
  
  Breakpoints Set in Task List: You have set breakpoints in the ABAP code that is executed as part of a task list.
  Execution Mode: The task list is being executed in a mode that does not support debugging (e.g., background processing).
  Incorrect Configuration: The task list may not be configured to run in a mode that allows for debugging.
  
  Solution:
  
  
  Run in Debugging Mode: To hit the breakpoints, you need to run the task list in a mode that supports debugging. This can typically be done by:
  
  Executing the task list in the foreground instead of the background.
  Using transaction STC01 to start the task list and selecting the option to run it in debug mode.
  
  
  
  Remove Breakpoints: If debugging is not necessary, you can remove the breakpoints from the code to avoid this error.
  
  
  Check Task List Configuration: Ensure that the task list is configured correctly to allow for debugging. This may involve checking the settings in the task list or the associated jobs.
  
  
  Use Debugging Tools: If you need to debug a task list that runs in the background, consider using tools like the ABAP Debugger or Transaction ST22 to analyze dumps or errors that occur during execution.
