IF sy-tcode = ‘MB1A’.
  IF i_mseg-bwart = ‘261’ OR i_mseg-bwart = ‘262’.
    IF l_rsnum = ”.
      SELECT SINGLE rsnum FROM afko INTO l_rsnum
        WHERE aufnr = i_mseg-aufnr.
    ENDIF.
    IF it_resb[] IS INITIAL.
      SELECT aufnr matnr INTO
        CORRESPONDING FIELDS OF TABLE it_resb FROM resb
        WHERE rsnum = l_rsnum.
    ENDIF.
    READ TABLE it_resb INTO it_resb WITH KEY matnr = i_mseg-matnr.
    IF sy-subrc <> 0.
    MESSAGE ‘生产订单组件清单中有不包含的物料!’ TYPE ‘E’.
