HI Pavan ,

try like this, its working correctly.

data: er_data_changed type ref to cl_alv_changed_data_protocol.

FIELD-SYMBOLS: <zfield> TYPE ANY.

ASSIGN er_data_changed->mp_mod_rows->* TO <zfield>.

Check out the entire program.

TYPE-POOLS: SLIS.

data: er_data_changed type ref to cl_alv_changed_data_protocol.

FIELD-SYMBOLS: <zfield> TYPE ANY.

DATA: T_SFLIGHT     TYPE STANDARD TABLE OF SFLIGHT.

DATA: IS_LAYOUT_LVC TYPE LVC_S_LAYO.

DATA: IT_EVENTS     TYPE SLIS_T_EVENT.

DATA: LT_EVENT      TYPE SLIS_ALV_EVENT.

DATA: L_REPORT      TYPE SY-REPID.

START-OF-SELECTION.
*

IS_LAYOUT_LVC-EDIT = 'X'.

LT_EVENT-NAME      = 'DATA_CHANGED'.

LT_EVENT-FORM      = 'ALV_DATA_CHANGED'.

APPEND LT_EVENT TO IT_EVENTS.

*

L_REPORT = SY-REPID.

*

SELECT * UP TO 10 ROWS INTO TABLE T_SFLIGHT

    FROM SFLIGHT.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'

    EXPORTING

      I_CALLBACK_PROGRAM = L_REPORT

      I_STRUCTURE_NAME   = 'SFLIGHT'

      IS_LAYOUT_LVC      = IS_LAYOUT_LVC

      IT_EVENTS          = IT_EVENTS

    TABLES

      T_OUTTAB           = T_SFLIGHT.

FORM ALV_DATA_CHANGED USING

         ER_DATA_CHANGED TYPE REF TO CL_ALV_CHANGED_DATA_PROTOCOL.

DATA: LS_GOOD TYPE LVC_S_MODI.

ASSIGN er_data_changed->mp_mod_rows->* TO <zfield>.

LOOP AT ER_DATA_CHANGED->MT_GOOD_CELLS INTO LS_GOOD.

Are you using OOPS ALV? If so then we need to define an event and a method to handle changed data.

class lcl_event_receiver definition.

public section.

     methods:
       handle_data_changed
          for event data_changed of cl_gui_alv_grid
              importing er_data_changed.

class lcl_event_receiver implementation.

method handle_data_changed.

data: ls_good type lvc_s_modi.

data: ls_fld1_new like table-field1.

loop at er_data_changed->mt_good_cells into ls_good.
case ls_good-fieldname.

WHEN 'FIELD1'.

* This Method below returns your new value

CALL METHOD er_data_changed->get_cell_value

EXPORTING i_row_id = ls_good-row_id

i_fieldname = ls_good-fieldname

IMPORTING e_value = ls_fld1_new.

* Do your processing with the changed value.

endcase.

endloop.
