Answer 1

*  Prüfung, ob Berechtigung für die Werke existiert
  SELECT * FROM T001W INTO TABLE AW_HLP_T001W
                      WHERE WERKS IN AW_WERKS.
  DESCRIBE TABLE AW_WERKS LINES SY-TFILL.
  IF SY-TFILL > 0.
    FLG_SELECT = 'X'.
  ENDIF.
<b> clear aw_hlp_t001w-werks.                       " note 124769, ver.04
  collect aw_hlp_t001w.                           " note 124769, ver.04</b>
  LOOP AT AW_HLP_T001W.
    AUTHORITY-CHECK OBJECT 'M_IS_WERKS'
             ID 'MCINF' FIELD AW_MCINF
             ID 'WERKS' FIELD AW_HLP_T001W-WERKS.
There must be a reason to add an empty line, which causes the silly authority check. As far as I understand Note 124769 you have got to add  plant ' '. See Note 408003: ."Create an authorization for the authorization object M_IS_WERKS which contains the value WERK =  . Refer to Note 124769."
