Switch on different types of debugging

If a program is executed, debugging can be switched on as follows:

• Executable programs, FM, methods or transactions.
  • Enter /h in the command field or select menu item System -> Utilities -> Debug Screen
    • ABAP statements and screen logic are debugged.
  • Enter /ha in the command field or select menu item System -> Utilities -> Debug ABAP
    • ABAP statements and screen logic are debugged.
  • Enter /hs in the command field or select menu item System -> Utilities -> Debug System
    • Not only your program but also the system programs are debugged.

NB: /h is more commonly used amongst three.
