Function module GET_GLOBALS_FROM_SLVC_FULLSCR issue

[Former Member]

Hi experts,

I am using the below code,

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

       EXPORTING

         i_callback_program      = sy-cprog

         i_callback_user_command = 'USER_COMMAND'    <--------------- for this

         i_callback_top_of_page  = 'TITLE'

         is_layout               = gd_layout

         it_fieldcat             = it_fieldcat

         i_save                  = 'X'

       TABLES

         t_outtab                = it_final

       EXCEPTIONS

         program_error           = 1

         OTHERS                  = 2.

     IF sy-subrc = 1.

       MESSAGE 'Program Error'(004) TYPE 'E'.

     ENDIF.

     REFRESH: it_fieldcat.

   ENDIF.

FORM user_command USING r_ucomm   TYPE sy-ucomm

                         sel_field TYPE slis_selfield.

   DATA: it_grid TYPE REF TO cl_gui_alv_grid,

         lv_is_valid.

   DATA: lv_flag_crt TYPE char1,

         lv_flag_chg TYPE char1.

   CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

     IMPORTING

       e_grid = it_grid.

   CALL METHOD it_grid->check_changed_data

     IMPORTING

       e_valid = lv_is_valid.

if lv_is_valid is not initial and r_ucomm = '&DATA_SAVE'.

Success message .

endif.

The problem is always i am getting lv_is_valid is 'X'. whenever the it_grid get filled lv_is_valid become 'X'.

I need only when there is a change in inputfields of report output(editable columns).  Now always i am getting success message.

Please suggest me a solution.

Thanks & regards

Venkat

Hi Venkat,

you need to take the data in another internal table before passing to the Reuse ALV FM, Then you have to compare the two tables. If not equal then there is a change in the output.

FORM user_command USING ucomm TYPE sy-ucomm

      slis_self  TYPE slis_selfield.

  CASE ucomm.

    WHEN '&DATA_SAVE'.

      IF  lt_final_1  <> lt_final.

     endif.

   endcase.

Hi Venkatram's

In your case user can only edit the field not to add the row and delete the row.

Loop at old_internal table.

read new_internal table " key field that cann't be change.

               and put the logic for the fresh value "

endloop.
