Hi,

Use the below code and declare as below :

data : gt_listheader TYPE slis_t_listheader,
         gs_line TYPE slis_listheader,

  PERFORM f_build_alv_title USING gt_listheader[].

&--------------------------------------------------------------------*
*&      Form  f_build_alv_title
*&--------------------------------------------------------------------*
*       text : ALV Header Section
*---------------------------------------------------------------------*
FORM f_build_alv_title
    USING lt_top_of_page
    TYPE slis_t_listheader.

  CLEAR gs_line.
  
*Customer Number

  if not itab[] is initial.

loop at itab.
    CLEAR: gs_line.
    gs_line-typ  = s.
    gs_line-key  = 'Customer'(015).
    gs_line-info = itab-kunnr.
    APPEND gs_line TO lt_top_of_page.
endloop.
endif.

   CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
         EXPORTING
           i_callback_program                = gv_repid
           i_callback_user_command           = 'F_USER_COMMAND'
           i_callback_top_of_page            = 'TOP_OF_PAGE'
           is_layout                         = gt_layout
           it_fieldcat                       = gt_fieldcat[]
           it_sort                           = gt_sort[]
           i_save                            = 'A'
           it_events                         = gt_event[]
    TABLES
      t_outtab                          = gt_output
         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 : Top of Page event
*---------------------------------------------------------------------*

FORM top_of_page.

  CALL FUNCTION 'REUSE_ALV_COMMENTARY_WRITE'
    EXPORTING
