How to read Screen Stack

[Former Member]

Hi ABAP Gurus,

I have a requirement where i need to read Screen Stack.

The stack in debug mode is -

Debug 1.jpg

I need to get the highlighted value (transaction).

I tried FM 'SYSTEM_CALLSTACK' and it only gives ABAP stack details.

Debug 2.jpg

I need a way to read Screen Stack only.

Any guidance would be highly appreciated.

Take a look at class CL_TPDA_CONTROL, methods IF_TPDA_CONTROL~GET_DYNPRO_STACK.

Hi Raymond,

Thanks for bringing a viewpoint.

I have used below code -

DATA: zob1 TYPE REF TO cl_tpda_control.

  CREATE OBJECT: zob1.

*DATA INCL_EM_STACK TYPE FLAG.

  DATA stacktab      TYPE tpda_sys_dy_stacktab.

  TRY.

      CALL METHOD zob1->get_dynpro_stack

        EXPORTING

          incl_em_stack = ' '

        IMPORTING

          stacktab      = stacktab.

    CATCH cx_tpda_sys_dyn_spa .

    CATCH cx_tpda_sys_dyn_notyet .

    CATCH cx_tpda_sys_dyn_notcons .

    CATCH cx_tpda_sys_dyn_nody .

    CATCH cx_tpda_sys_dyn_nodata .

    CATCH cx_tpda_sys_comm .

    CATCH cx_tpda_sys_version .

    CATCH cx_tpda_sys_internal .

  ENDTRY.

But,

An exception (CX_TPDA_SYS_COMM_SLAVENOTCONN) occurred and stacktab[] is coming empty.

Hello Guys,

I could not find any working solution for this problem so i had to change the design.

Hi Ankit,

I think you tried to read the original transaction in which SM30 was called.

You can achieve the same with below:

    DATA: sy_tcode TYPE sy-tcode.

    CALL 'GET_PARAM_TCOD' ID 'PTCOD' FIELD sy_tcode.

SY_TCODE is your YTV023(SM30)
