使用SNOTE能查询到系统里implement的note列表:

可以使用下面的function module来查询:

DATA: ls_note TYPE bcwbn_note.
DATA: l_valid TYPE bcwbn_bool.
ls_note-key-numm = '1617787'.
CALL FUNCTION 'SCWB_NOTE_READ'
  EXPORTING
    iv_read_corr_instructions  = 'X'
    iv_read_short_text         = 'X'
    iv_read_all_texts          = 'X'
    iv_read_validity           = 'X'
  CHANGING
    cs_note                    = ls_note
  EXCEPTIONS
    note_not_found             = 1
    language_not_found         = 2
    unreadable_text_format     = 3
    corr_instruction_not_found = 4
    OTHERS                     = 5.

WRITE: / sy-subrc.

如果输入一个不存在的note number，会返回note_not_found的exception
