What is Debugging?

•Tool used to identify and eliminate errors in ABAP programs

•Allows the verification of program logic in a step-by-step manner by examining the results of individual statements

Important Debugging Functions

  • Single Step   -Processes the next program line
  • Execute        -Allows the change of data contents during debugging
  • Continue      -Processing continues until the next breakpoint (or end of program) is encountered
  • Breakpoint    -Identifies breakpoints
  • Watchpoint   -Interrupts the program when there is a change in a field
  • Replace        -Allows the change of data contents during debugging

Examining the Value of Variables

examining the value of variables
examining the value of variables
in order to examine the value of the variable we just need to click on the line and breakpoint will be created, we just need to make sure we select external breakpoint otherwise the code will not trigger.
by double clicking the variable, we can see the value and we can edit the value as well.
like variables we can view the content of the internal table. debugging is very helpful when we have to find an issue in SAP ABAP or we have to fix any issue.

we can execute line by line code by pressing F6 if we want to go into Function Module call we can press F5 to execute program we press F8.
