I had similar kind of requirement. Have a look at below code. It will help you. You can execute it. You can see the report output which contains two header lines.
REPORT  ztestvib    MESSAGE-ID zz  LINE-SIZE 50.
TYPE-POOLS: slis.
DATA: x_fieldcat TYPE slis_fieldcat_alv,
      it_fieldcat TYPE slis_t_fieldcat_alv,
      l_layout TYPE slis_layout_alv,
      x_events TYPE slis_alv_event,
      it_events TYPE slis_t_event.
DATA: BEGIN OF itab OCCURS 0,
      vbeln LIKE vbak-vbeln,
      posnr LIKE vbap-posnr,
      male TYPE i,
      female TYPE i,
     END OF itab.
SELECT vbeln
       posnr
       FROM vbap
       UP TO 20 ROWS
       INTO TABLE itab.
x_fieldcat-fieldname = 'VBELN'.
x_fieldcat-seltext_l = 'VBELN'.
x_fieldcat-tabname = 'ITAB'.
x_fieldcat-col_pos = 1.
APPEND x_fieldcat TO it_fieldcat.
CLEAR x_fieldcat.
x_fieldcat-fieldname = 'POSNR'.
x_fieldcat-seltext_l = 'POSNR'.
x_fieldcat-tabname = 'ITAB'.
x_fieldcat-col_pos = 2.
APPEND x_fieldcat TO it_fieldcat.
CLEAR x_fieldcat.
x_fieldcat-fieldname = 'MALE'.
x_fieldcat-seltext_l = 'MALE'.
x_fieldcat-tabname = 'ITAB'.
x_fieldcat-col_pos = 3.
APPEND x_fieldcat TO it_fieldcat.
CLEAR x_fieldcat.
x_fieldcat-fieldname = 'FEMALE'.
x_fieldcat-seltext_l = 'FEMALE'.
x_fieldcat-tabname = 'ITAB'.
x_fieldcat-col_pos = 3.
APPEND x_fieldcat TO it_fieldcat.
CLEAR x_fieldcat.
x_events-name = slis_ev_top_of_page.
x_events-form = 'TOP_OF_PAGE'.
APPEND x_events  TO it_events.
CLEAR x_events .
l_layout-no_colhead = 'X'.
CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
  EXPORTING
    i_callback_program = sy-repid
    is_layout          = l_layout
    it_fieldcat        = it_fieldcat
    it_events          = it_events
  TABLES
    t_outtab           = itab
  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.
*&      Form  top_of_page
      text
FORM top_of_page.
*-To display the headers for main list
  FORMAT COLOR COL_HEADING.
  WRITE: / sy-uline(103).
  WRITE: /   sy-vline,
        (8) ' ' ,
             sy-vline,

  FORMAT COLOR OFF.
ENDFORM.                    "top_of_page
The header lines are as below:
VBELN      POSNR      MALE       FMALE
I hope it helps.
