Regarding ALV GRID Display

Hi Experts,

I am facing the problem regarding ALV grid display.....

I made a field catalog using Perform like

STATICS : p_cnt TYPE sy-index.
  CLEAR p_cnt.

 PERFORM sub_make_field_cate USING :

*--------------------------------------------------------------------------------------------  *
* |       Itab       |      Fldname       |      Reftab     |    reffld     |      text       |
*
*--------------------------------------------------------------------------------------------  *
* |      colpos      |       o/p_len      |     Emphasize   |      key      |      do_sum     |
*
*--------------------------------------------------------------------------------------------  *
* |     no_zero      |        no_out      |      HotSpot    |     just      |     exponent    |
*
*--------------------------------------------------------------------------------------------  *
* |     Decimal      |
*  ------------------ *

         'ALV'           'PERNR'              ' '             ' '            'Personnel Number'
            p_cnt             ' '                  ' '             ' '              ' X '
            ' '               ' '                  'X '             ' '              ' '
            ' ' ,

and it display using

is_layout-zebra = 'X'.
is_layout-colwidth_optimize = 'X'.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

Now, my problem is I didn't get any application tool bar options in ALV Grid display.

Is this need for any settings like PF-Status settings....

If any settings required, please give me those details ...........

My delivery time is coming soon.... please help me in this regard...

Thanks in advance
