Here are some potential causes, solutions, and related information for this error:
  Causes:
  
  Incorrect Screen Sequence: The program may be trying to navigate to a screen that is not defined or is incorrectly sequenced.

  Debugging: Use the ABAP debugger to step through the program and identify where the error occurs. Look for any unexpected behavior in the screen transitions.
  Review Dynamic Screen Changes: If screens are being changed dynamically, ensure that the logic is sound and that all necessary checks are in place to prevent invalid screen transitions.
  Check for Missing Screens: Ensure that all screens referenced in the program are available and correctly defined in the screen painter.
