select sum( zjban ) sum( zbban )

     from zsdtcham 

      into (itab-zjban, itab-zbban)
  where audat => l_date
      and audat =< l_date2.
  append itab.
  clear itab.
  endselect.

Incorrect nesting: For the statement "ENDSELECT", there is no open  

structure introduced by "SELECT".  

이렇게 되네요? 뭐가 문제일까요?
