Debugging is the process of evaluating a program line by line to identify errors and ensure it runs as expected. The ABAP debugger is essential for understanding program flow, identifying logical errors, and allows variable inspection at runtime. There are two debuggers: the classic version, which is outdated, and the new version that offers a modern interface and improved debugging capabilities.

3. What is Debugging?
Definition:
Debugging is a process of running a program
“line by line” or by “Section”
and examine the values of Variables or look at
values passed into Functions and let you figure out
whether it is running the way you expected.

4. Why we need to do Debugging?
 ABAP Debugger helps to understand
program flow at runtime.
 ABAP Debugger is the efficient means of
identifying logical errors in programs.
 Field contents can be displayed or
changed at runtime.
 Programs can be stopped at a particular
statement, event, subroutine, function
module or system exceptions.

5. How to do Debugging?
To Debug an ABAP program, we need to
enter into ABAP Debugger at run time of
an ABAP program.
There are two types of Debuggers:
1. The Classic ABAP Debugger
2. The New ABAP Debugger

6. The Classic ABAP Debugger
The Classic ABAP Debugger, with its old
user interface and its limitations to debug
certain types of ABAP programs. It is now
not widely in use.

8. The New ABAP Debugger
The New ABAP Debugger, with its state of
the art and flexible user interface, can be
used to debug all types of ABAP
programs. It provides many new features
which improve our efficiency of debugging,
both in ABAP support and development.

10. How to Enter in to Debugger?
Option 1:
Set Break-Point at a particular statement of
any ABAP program.
 Before start of program execution
Options 2:
Type /H in Command Field and press Enter
 While running a Program
