Not Getting Checkboxes properly..

Question

Hi.
I used this code to put checkboxes. But I am getting checkboxes in each column instead of data.
But I want checkboxes only at the starting.
Please help me out...
CODE:
TYPES : BEGIN OF st_ekko,
          check(1),
          ebeln TYPE ekko-ebeln,   
          bstyp TYPE ekko-bstyp,  
          bsart TYPE ekko-bsart,   
          aedat TYPE ekko-aedat,   
          ernam TYPE ekko-ernam,  
        END OF st_ekko.
data : it_ekko TYPE STANDARD TABLE OF st_ekko,
         wa_ekko LIKE LINE OF it_ekko,
         it_fieldcat TYPE slis_t_fieldcat_alv,
         wa_fieldcat LIKE LINE OF it_fieldcat.
START-OF-SELECTION.
  SELECT ebeln bstyp bsart aedat ernam
    FROM ekko
    INTO CORRESPONDING FIELDS OF TABLE it_ekko
   WHERE ebeln IN so_ebeln.
  wa_fieldcat-fieldname = 'CHECK'.
  wa_fieldcat-input     = 'X'.
  wa_fieldcat-col_pos = 1.
  wa_fieldcat-input = 'X'.
  wa_fieldcat-edit = 'X'.
  wa_fieldcat-checkbox = 'X'.
  APPEND wa_fieldcat TO it_fieldcat.
  wa_fieldcat-fieldname = 'EBELN'.
  wa_fieldcat-seltext_l = 'Purchase document number'.
  wa_fieldcat-col_pos = 2.
  wa_fieldcat-no_zero = 'X'.
  APPEND wa_fieldcat TO it_fieldcat.
  wa_fieldcat-fieldname = 'BSTYP'.
  wa_fieldcat-seltext_l = 'Purchasing Document Category'.
  wa_fieldcat-col_pos = 3.
  APPEND wa_fieldcat TO it_fieldcat.
  wa_fieldcat-fieldname = 'BSART'.
  wa_fieldcat-seltext_l = 'Purchasing Document Type'.
  wa_fieldcat-col_pos = 4.
  APPEND wa_fieldcat TO it_fieldcat.
  wa_fieldcat-fieldname = 'AEDAT'.
  wa_fieldcat-seltext_l = 'Created On'.
  wa_fieldcat-col_pos = 5.
  APPEND wa_fieldcat TO it_fieldcat.
  wa_fieldcat-fieldname = 'ERNAM'.
  wa_fieldcat-seltext_l = 'Created By'.
  wa_fieldcat-col_pos = 6.
  APPEND wa_fieldcat TO it_fieldcat.
CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
    EXPORTING
      i_callback_program       = sy-repid
      is_layout                     = wa_layout
      it_fieldcat                    = it_fieldcat
    TABLES
      t_outtab                 = it_ekko[]
    EXCEPTIONS
      program_error            = 1
      OTHERS                   = 2.

I think you need:
clear: wa_fieldcat.
between each column definition e.g.
clear: wa_fieldcat.
wa_fieldcat-fieldname = 'CHECK'.
wa_fieldcat-input = 'X'.
wa_fieldcat-col_pos = 1.
wa_fieldcat-input = 'X'.
wa_fieldcat-edit = 'X'.
wa_fieldcat-checkbox = 'X'.
APPEND wa_fieldcat TO it_fieldcat.
clear: wa_fieldcat.
wa_fieldcat-fieldname = 'EBELN'.
wa_fieldcat-seltext_l = 'Purchase document number'.
wa_fieldcat-col_pos = 2.
wa_fieldcat-no_zero = 'X'.
APPEND wa_fieldcat TO it_fieldcat.
