Function module to find the columns in Internal table

Former Member — Mon, 19 Dec 2005 11:32:42 GMT

Hi Group,

Is there any function module which displays the columns of the internal table. I guess there is one cos when we debug any program and select the "Tables" button while debugging and enter an internal table and then do a "Find" the pop up which comes up shows the internal table columns. As this functionality is in the debugger which I cannot debug hence was wondering if some one has come across any such function module. Thanks in advance.

Hi Ankur,

Use the above FM.

It works fantastic.

Hi again,

1. In the above FM

Pass Program as SY-REPID (U cann pass other prg name also)

in FieldName Pass the name of the internal table

eg. 'ITAB'

2. This FM will give u the details of the

internal table.

The u can display the COMPONENTS table

using ALV or anyother method u like.

Thanks, But can some one tell me which is the function module which the abap debugger uses to display the internal table columns while debugging.

Hi again,

1. I am not sure, but the abap debugger

uses system C functions

(and not a normal function module)

for such purpose.

Please award points to helpful answers.

I would like to know whether it is a function module or a c function, If C function then what it is? Cos this is exactly what I am trying to achieve, I tried understanding the ABAP debugger program SAPMSSY3 screeb no 142 , couldn't see where is the coding done when we press the button find it has the Status as "TAAB" but couldn't see the code. Any help will be appreciated.
