ALV in Module Pool

[Former Member]

Hi Gurus,

I am displaying ALV on a module Pool Dialog screen as follows.

Data : v_alv_grid TYPE REF TO cl_gui_alv_grid.

CALL METHOD V_ALV_GRID->SET_TABLE_FOR_FIRST_DISPLAY
      EXPORTING
        IS_LAYOUT                     = X_LAY
        I_SAVE                        = 'X'
      CHANGING
        IT_OUTTAB                     = T_CHECK
        IT_FIELDCATALOG               = T_FCAT
      EXCEPTIONS
        INVALID_PARAMETER_COMBINATION = 1
        PROGRAM_ERROR                 = 2
        TOO_MANY_LINES                = 3
        others                        = 4.
    IF SY-SUBRC <> 0.
      MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
                 WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.

The table "T_Check" has a check box field. When the user checks any check box on the ALV screen, how to get that value back into the program?

I am unable to read that check box.

Could you tell me what else I have to code?

Hi,

If using OO ALV, then use this code when you click SAVE button:-

CASE sy-ucomm.
  WHEN 'SAVE'.
* to reflect the data changed into internal table
    DATA : ref_grid TYPE REF TO cl_gui_alv_grid. "new
 
    IF ref_grid IS INITIAL.
      CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
        IMPORTING
          e_grid = ref_grid.
    ENDIF.
 
    IF NOT ref_grid IS INITIAL.
      CALL METHOD ref_grid->check_changed_data.
    ENDIF.

   " at this point your internal table is modified from alv output.

    " and then use refresh_table_display
    CALL METHOD ref_grid->refresh_table_display.
    " to refresh the data from internal table back to alv output.
 
ENDCASE.

Hope this helps you.

Hi,

Please do like this.

FORM user_command USING r_ucomm LIKE sy-ucomm
                        r_selfield TYPE slis_selfield.


  DATA: gd_repid LIKE sy-repid, "Exists
        ref_grid TYPE REF TO cl_gui_alv_grid.

 
  CASE r_ucomm.
    WHEN 'PROCESS'.

      IF ref_grid IS INITIAL.
        CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
          IMPORTING
            e_grid = ref_grid.
      ENDIF.
      IF NOT ref_grid IS INITIAL.
        CALL METHOD ref_grid->check_changed_data .
      ENDIF.

      LOOP AT it_error INTO w_error WHERE check = 'X'.
       
      ENDLOOP.
      r_selfield-refresh = 'X'. 
encase.

thanks ,

kat.
