Hi,

Simple steps.....

For displaying the column names you have to add field catelog.

DATA : w_fieldcat TYPE slis_fieldcat_alv,

i_fieldcat TYPE slis_t_fieldcat_alv,

gs_layout TYPE slis_layout_alv.

w_fieldcat-tabname = 'it_details'.

w_fieldcat-fieldname = 'Your first field name'

w_fieldcat-outputlen = '6'.

w_fieldcat-col_pos = '1'.

w_fieldcat-row_pos = '1'.

APPEND w_fieldcat TO i_fieldcat.

CLEAR w_fieldcat.

w_fieldcat-tabname = 'it_details'..

w_fieldcat-fieldname = 'Your second field name'.

w_fieldcat-do_sum = c_x.

w_fieldcat-outputlen = '13'.

w_fieldcat-col_pos = '2'.

w_fieldcat-row_pos = '1'.

w_fieldcat-seltext_l = c_seltext_l1.

APPEND w_fieldcat TO i_fieldcat.

CLEAR w_fieldcat.

After this call FM

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

i_callback_program = 'Your program name'

is_layout = gs_layout

it_fieldcat = i_fieldcat[]

it_sort = wa_sort1

TABLES

t_outtab = it_details.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

Pls. reward if useful.....
