• What is the cause and solution for SAP error message 00062 - CALL SCREEN not allowed in subscreens (program error) ?

  The SAP error message "00062 CALL SCREEN not allowed in subscreens (program error)" typically occurs when there is an attempt to use the CALL SCREEN statement in a subscreen context, which is not permitted in SAP ABAP programming. This error indicates that the program is trying to call a screen from within a subscreen, which is not allowed according to the SAP programming model.
  Cause:
  
  Improper Use of CALL SCREEN: The most common cause of this error is the incorrect use of the CALL SCREEN statement in a subscreen. Subscreens are meant to be included in a main screen and should not initiate their own screen flow.
  Program Logic Error: There may be a logical error in the program where the flow of control is incorrectly designed, leading to an attempt to call a new screen from a subscreen.
  
  Solution:
  
  Review the Code: Check the ABAP code where the CALL SCREEN statement is used. Ensure that it is only used in the main screen or in a proper context where it is allowed.
  Use of Subscreens: If you need to display additional information or functionality, consider using subscreens properly. You can use SET SUBSCREEN to include subscreens in the main screen instead of trying to call a new screen.
  Refactor Logic: If the logic requires navigating to a different screen, consider restructuring the program to handle the screen transitions correctly. This may involve moving the CALL SCREEN statement to a different part of the program where it is valid.
  Debugging: Use the ABAP debugger to trace the program execution and identify where the CALL SCREEN is being invoked from a subscreen. This can help pinpoint the exact location of the error.
