Question

How can I show the value inside a structure? see below the example:

DATA: BEGIN OF line,
        col1 TYPE i,
        col2 TYPE i,
      END OF line.

DATA: itab LIKE TABLE OF line,
      jtab LIKE TABLE OF line.

DO 3 TIMES.
  line-col1 = sy-index.
  line-col2 = sy-index ** 2.
  APPEND line TO itab.
ENDDO.

MOVE itab TO jtab.

line-col1 = 10. line-col2 = 20.
APPEND line TO itab.


IF itab GT jtab.
  WRITE / 'ITAB GT JTAB'.
ENDIF.

Write: itab, jtab.

because i want to know why itab is greater than jtab?.

Answer 1

If you want to see the contents of a field purely for debugging purposes you can also just put a break point in your code and look at the contents in debugger.

Just don’t leave the break point in productive code!

break-point. 
"or use break yourusername  <= this use is safer

EDIT:
You can also just use a session break-point, which does not require you to change the code (and will only be applicable to your user for the duration of the session):

In the system where you are running the program:

• Open the Program
• Select the line that you would like the program to stop on

• Click the session Break-point button

  

The break-point icon will appear next to the line (you can also just click in the place where the icon appeared, to set/delete the break-point).
