No data returned from class method to PBO

I want to return record of table from abap method, which is field of class but nothing is returned to the variable in PBO

definition in class

 data MS_ZORK_JG_SETTING type ZORK_JG_SETTING .

  methods GET_MS_ZORK_JG_SETTING
    returning
      value(MS_ZORK_JG_SETTING) type ZORK_JG_SETTING .

MS_ZORK_JG_SETTING is a data type which contains data from ZORK_JG_SETTING transparent table, filled properly using other method, so there is a correct data in this variable

in pbo of the screen i wanted to assign returned value to variable of the same type as returned


MODULE pbo_0102 OUTPUT.

DATA: wa_jg_setting TYPE zork_jg_setting.

  wa_jg_setting = go_bukrs_conf->get_ms_zork_jg_setting( ).

  MOVE-CORRESPONDING wa_jg_setting TO zork_jg_setting.


ENDMODULE.

But wa_jg_setting is empty. Tell me why and how to repair that?

Place of invoking screen

DATA: go_bukrs_conf TYPE REF TO zork_cl_scr_bukrs_conf.
CREATE OBJECT go_bukrs_conf
        EXPORTING
          pa_bukrs = '3020'.

      CALL SCREEN 102.

And get_ms_zork_jg_settings method. I am assigning a value of field to a formal parameter

  method GET_MS_ZORK_JG_SETTING.
    ms_zork_jg_setting = ms_zork_jg_setting."zwracana wartosc to pole/ atrybut
  endmethod.

The line

ms_zork_jg_setting = ms_zork_jg_setting.

is useless, as you assign the value of the return parameter to itself.

Generally speaking, var = var is always non-sense.

Probably you want to do:

ms_zork_jg_setting = me->ms_zork_jg_setting.
