you would need to use Data change events of ALV to achive this functionality. check BALCV* alv programs for thier functionality in SE38,.

Hi

You need to include a edit field in the fieldcatalog to make the ALV editable .

fieldcat-edit = 'X'.

after changing the values in ALV , press enter .

and the internal table used for ALV will have the changed values .

Try using the structure LVC_S_STYLE.

Declare a field of type LVC_S_STYLE in ur internal table,

In the class CL_GUI_ALV_GRID, you have the methods like MC_STYLE_ENABLED and MC_STYLE_DISABLED.

sample code:

ls_stylerow type LVC_S_STYLE.

LOOP AT it_itab INTO wa_itab.

IF wa_itab-field1(this will be the field by which u will validate) = 'X'.

ls_stylerow-fieldname = 'FIELD2' . "Field which you want to grey

ls_stylerow-style = cl_gui_alv_grid=>mc_style_disabled. "set field to disabled

APPEND ls_stylerow TO wa_itab-field_style.

MODIFY it_itab FROM wa_itab.

ENDIF.

ENDLOOP.

and after this write the logic to update the table on saving.

HI,

To achive ur target u need to use few methods.

CLASS-METHODS : data_changed

FOR EVENT data_changed OF cl_gui_alv_grid

IMPORTING er_data_changed.

In this method it gets the what ever u have changed in the alv screen to the previous version.

keep a loop for the er_data_changed as given below.

DATA : changed_data TYPE lvc_s_modi.

DATA : lv_change TYPE c,

lv_werks TYPE t001w-werks,

gv_error_in_data TYPE c.

LOOP AT er_data_changed->mt_mod_cells INTO changed_data.

endloop.

Write a modify statement inside the loop to update the database table as well as the internal table.

The whole code should in save button u have placed on the alv screen.

Hi Bhaskar,

To make fields editable in ALV, while creating the field catalog for ALV, use:-

wa_field-edit = 'X'. " to make a field editable

To check the data changed in ALV, use code:-

*----------------------------------------------------------------------*
ALV GRID Display
*----------------------------------------------------------------------*
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
  EXPORTING
    i_callback_program                = sy_repid " report id
    i_callback_user_command           = 'USER_COMMAND' " to handle user command
    it_fieldcat                       = it_field " for field catalog
    it_sort                           = it_sort " for sort records info
  TABLES
    t_outtab                          = it_final "internal table with records
  EXCEPTIONS
    program_error                     = 1
    OTHERS                            = 2.

  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

*----------------------------------------------------------------------*
Sub-routine USER_COMMAND
*----------------------------------------------------------------------*
FORM user_command USING v_okcode LIKE sy-ucomm selfield TYPE slis_selfield.

* assign the function code to variable v_okcode
  v_okcode = sy-ucomm.

* handle the code execution based on the function code encountered
  CASE v_okcode.

* when the function code is EXECUTE then process the selected records
    WHEN 'EXECUTE'.

*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.

* refresh the ALV Grid output from internal table
      selfield-refresh = c_check.
ENDCASE.

Hope this solves your problem.

Hi,

If edited value wants to update in Database table You should use event as 'USER_COMMAD'. Once you click on SAVE there you have to call BDC.

FROM TABLE IT_OUT_TAB INTO WA_OUT_TAB INDEX WA_SELFIELD-TABINDEX.

IF SY-SUBRC = 0.

SET PARAMETER ID: 'BLN' field WA_OUT_TAB-BELNR.

CALL TRANSACTION 'FB03' .

EDNIF.

ENDFORM.

Hi,

you want to mention this ls_fieldcatalog-edit = 'X' in the field catalog and use i_save = 'X' in the FM

CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'

EXPORTING

i_callback_program = v_repid

is_layout = gs_layout

it_fieldcat = i_fieldcat[]

it_events = i_event[]

it_sort = i_sort[]

i_save = 'X'

TABLES

t_outtab = i_final_1

EXCEPTIONS

program_error = 1

OTHERS = 2.
