Hello Priya,
1) If u want to make fields of an ALV to be editable based on certain conditons then see the following code.
First create an extra field in ur internal table.
        celltab TYPE lvc_t_styl,
After that pass this field to the layout.
  gw_layout-stylefname = 'CELLTAB'.
Here the layout structure is defined as
gw_layout TYPE lvc_s_layo
now based on the condition u can set the fields editable or non editable.U can check the following code.
  DATA: ls_celltab TYPE lvc_s_styl.
  ls_celltab-fieldname = 'CHK'.
  ls_celltab-style = cl_gui_alv_grid=>mc_style_disabled.
  MODIFY gw_final-celltab FROM ls_celltab
  TRANSPORTING style
  WHERE fieldname = ls_celltab-fieldname.
  IF sy-subrc NE 0.
    INSERT ls_celltab INTO TABLE gw_final-celltab.
  ENDIF.
Now if ur using OO-ALV then pass the layout to the method.
If ur going by Function modules then u need to call the following function module.
  gw_layout-stylefname = 'CELLTAB'.
  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
    EXPORTING
      i_callback_program       = sy-cprog
      i_callback_pf_status_set = 'PF_STATUS'
      i_callback_user_command  = 'USER_COMMAND'
      is_layout_lvc            = gw_layout
      it_fieldcat_lvc          = gi_fieldcat
    TABLES
      t_outtab                 = gi_final
    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.
2) If u want to read the changed contents from ALV grid back to ur program then use the following function modules.
    CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
        IMPORTING
          e_grid = l_ref1.
      CALL METHOD l_ref1->check_changed_data
        IMPORTING
          e_valid = lv_valid.
