By using Sort stage, sort the data in Descending order, then
use remove duplicates stage, set option as first occurrence

In case an explicit sort stage is used like inteh reply
above, the sort will be done on emp_id(key field) and the
salary. But remove duplicate will be done only on emp_id. I
guess that this might result in a warning like 'sort and
remove duplicates keys do not match'.
