Get the value of a field dynamically using system_callstack

Former Member — Mon, 06 Oct 2008 11:25:15 GMT

Hi Gurus...

My requirement is to get the value of a field used in a program which is available in my call stack while debugging.

I am using FM system_callstack but it just gives an internal table comprising of 3 fields programname, event type and event name.

I do not know how to retrieve the value of a variable being used in one of the programs.

My sample code is

CALL FUNCTION 'SYSTEM_CALLSTACK'

IMPORTING

et_callstack = l_cstack_tab. " internal table

READ TABLE l_cstack_tab INTO l_cstack_wa INDEX 4.

IF sy-subrc = 0 AND l_cstack_wa-progname IS NOT INITIAL.

l_evt_class = l_cstack_wa-progname.

then what shud I do.*********************

ENDIF.

Please help.

Hi,

Try using an external assign the read the call stack, e.g.

data: lv_name(30) type c,
       lv_lgbkz    type lvs_lgbkz.
 field-symbols: <fs> type any.


 lv_name = '(SAPLL03A)I_MLVS-LGBKZ'.
 assign (lv_name) to <fs>.
 if ( <fs> is assigned ).
...............
endif.

Where the value in lv_name is the program and variable name from the call stack.

Regards,

Darren

Hi Darren,

Thanks for the reply.

I am somehow not able to understand your solution. I will again explain my issue. I alraedy have the name of the program which I need to use at runtime.

The issue is that this program has the structure filled with data and I need this data at run time in another program so I am using the FM System_callstack. Using this I get the name of the program dynamically but how do I read this structure data.

I hope I am clear.

Please help.

Thanks,

Neha
