Hi rakhee,
First add a single charecter field into the internal table you want to display in the ALV.Then set the field cataloge and set the value for Checkbox as 'X'.it wil display the field as a check box.when you check the check box it will update the internal table also.
please check the below code.
TYPE-POOLS : slis.
TYPES : BEGIN OF st_mara.
TYPES : matnr TYPE mara-matnr.
TYPES : a,
END OF st_mara.
DATA : it_fieldcat TYPE slis_t_fieldcat_alv,
       wa_fieldcat LIKE LINE OF it_fieldcat.
DATA : it_mara TYPE TABLE OF st_mara.
SELECT * FROM mara
         INTO CORRESPONDING FIELDS OF TABLE it_mara UP TO 1 ROWS.
wa_fieldcat-col_pos = 1.
wa_fieldcat-fieldname = 'A'.
wa_fieldcat-checkbox = 'X'.
wa_fieldcat-edit = 'X'.
APPEND wa_fieldcat TO it_fieldcat.
CLEAR wa_fieldcat.
wa_fieldcat-col_pos = 2.
wa_fieldcat-fieldname = 'MATNR'.
APPEND wa_fieldcat TO it_fieldcat.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
  EXPORTING
    it_fieldcat = it_fieldcat
  TABLES
    t_outtab    = it_mara.
BREAK-POINT.
if you are using controls just call the method
  CALL METHOD grid1->check_changed_data.
grid1 is the instance of the ALV grid.
when the method is called you will get the internal table with the field marked as 'X'.
