Hi you can generate this code for your variable.
DATA lo_nd_flighttab TYPE REF TO if_wd_context_node.
    DATA lo_el_flighttab TYPE REF TO if_wd_context_element.
    DATA ls_flighttab TYPE wd_this->Element_flighttab.
    DATA lv_seatsmax TYPE wd_this->Element_flighttab-seatsmax.
  navigate from <CONTEXT> to <FLIGHTTAB> via lead selection
    lo_nd_flighttab = wd_context->get_child_node( name = wd_this->wdctx_flighttab ).
  @TODO handle non existant child
  IF lo_nd_flighttab IS INITIAL.
  ENDIF.
  get element via lead selection
    lo_el_flighttab = lo_nd_flighttab->get_element( ).
  @TODO handle not set lead selection
    IF lo_el_flighttab IS INITIAL.
    ENDIF.
  @TODO fill attribute
  lv_seatsmax = 1.
  set single attribute
    lo_el_flighttab->set_attribute(
      name =  `SEATSMAX`
      value = lv_seatsmax ).
in the value give the default value which ever you want.
Best regards,
