Please take a minute to format your code. The followin gis the correct comparison, assuming your date variable is a character and formatted as yymmdd.

input(Date_Stop,yymmdd8.) < today()

Your code appears like your stop_date is a character field. If so, then the following should work:

data have;
  input date_stop $;
  if input(Date_Stop,yymmdd8.) < today() then do;
    errordes5='Invalid Date_Stop';
  end ;
