Hi, <li>Check the below sample code how you have to get build internal table at run time.

*----------------------------------------------------------------------*
*       Form  GET_FIELDCAT_FROM_VARIANT
*----------------------------------------------------------------------*
*       Retrieve the fieldcatalog stored for the variant
*----------------------------------------------------------------------*
form get_fieldcat_from_variant using disvar    like disvariant
                                     itab_head type c
                                     itab_item type c.

  data: fieldcat_new type kkblo_t_fieldcat.

  call function 'REUSE_ALV_TRANSFER_DATA'
       exporting
            it_fieldcat = fieldcat
            is_layout   = layout
       importing
            et_fieldcat = fieldcat_kkb
            es_layout   = layout_kkb.

  call function 'LT_VARIANT_LOAD'
       exporting
            i_tabname           = itab_head
            i_tabname_slave     = itab_item
            i_dialog            = space
            i_user_specific     = 'X'
       importing
            et_fieldcat         = fieldcat_new
       changing
            ct_default_fieldcat = fieldcat_kkb
            cs_layout           = layout_kkb
            cs_variant          = disvar
       exceptions
            wrong_input         = 1
            fc_not_complete     = 2
            not_found           = 3
            others              = 4.

  if sy-subrc = 0.
    refresh fieldcat.
    call function 'REUSE_ALV_TRANSFER_DATA_BACK'
         exporting
              it_fieldcat = fieldcat_new
         importing
              et_fieldcat = fieldcat.

    clear: fieldcat_ln.
    modify fieldcat from fieldcat_ln transporting no_out
      where no_out <> 'X'.
  endif.
endform.                               " GET_FIELDCAT_FROM_VARIANT
