方案1：
DATA: l_time_stamp TYPE timestampl,
l_interval TYPE f,
l_new_time TYPE timestampl.
l_interval = '.2'.
GET TIME STAMP FIELD l_time_stamp.
WRITE: / l_time_stamp.
l_new_time = l_time_stamp + l_interval.
DO.
GET TIME STAMP FIELD l_time_stamp.
IF l_time_stamp >= l_new_time.
EXIT.
ENDIF.
ENDDO.
WRITE: / l_time_stamp.
WRITE: / 'waited for 200 millisecond'.
方案2：
WAIT UP TO '0.1' SECONDS.
