After making sure that the sort order of your data is in CODE DH_EVNM order then (Sort your existing data)

data want;
   set have;
   by code;
   if last.code;
run;

Your shown example is the most recent, not oldest, by datetime value.

The BY statement in the data step creates automatic variables First. and Last. for each by variable. These are 1/0 coded numeric variables so if the current record is the last one of a by group the If selects it for retention in the output data.
