Debugging

ABAP / 4 - Debugger is the developmentworkbench tool which allows you to stop a

program during its execution when a particularcondition is met

When the program is stopped , you can usethe debugger to display the contents of the

table and variable being used by the program .

Starting the ABAP / 4 Debugger inDifferent Ways

Method 1 : By Clicking the Execute button and enter/H in command box.

Method 2 : In ABAP / 4 editor, by executing a program

Choosing Program-->Execute -->Debugging

from the Menu.

Method 3 : Setting Breakpoint in the Program.

Database transaction or LUW

In ABAP debugger we can view and change data.

It also allow you to execute our program line by line.

Functions of the Debugger screen

Single step(F5) - Use this option to step through theprogram statement by statement. This allows you to branchinto subroutines and function modules, and to execute theseroutines step by step as well. Once a subroutine or function

module has been processed, control returns to thestatement following the CALL FUNCTION or PERFORMstatement.

Execute(F6)- Use this option to process a program line byline. All of the statements on the current line are processedin a single step. If you are positioned on a line that calls asubroutine and you choose Execute, the Debuggerprocesses the whole subroutine and then moves on to theline following the subroutine call. This allows you to jump

through the statements within the subroutine.

Functions of the Debugger screen

Return(F7) - The Debugger returns from a routine tothe point at which control returns to the main program.Use this option to return from a subroutine, function

module, or called program to the calling program. Continue(F8)- Use this option to process the program

up to the next dynamic or static breakpoint or up to thecursor position. If there are no more breakpoints in the

program and no cursor has been set, the system exitsdebugging mode and executes the rest of the programnormally.

Watch Points

In SAP ABAP a WatchPoint can be set to break theprogram at the point when the value of a filed in the

program changes. In SAP ABAP a maximum of 10WathPoints can be set in a session. This is a veryhandy tool if you want to break and debug the programonly from the point when a field under consideration

has the desired value.

1. Choose BreakpointCreate watchpointor thecorresponding pushbutton. The Create Watchpointdialog box appears:

Decide whether you want to set a local or global

Watch Points

If you want your watchpoint to be activated each timethe contents of the field change, the definition is nowcomplete, and you can return to the Debugger bypressing ENTER .

To create a conditional watchpoint, that is onlyactivated when a particular situation arises, choose oneof the following relational operators

Operator Meaning< Less than

= Greater than or equal

> Greater than
