I use a dataset containing dates
I would like to append new dates from another file but surely not add yet existing dates
So I would like to filter dates from new file considering the greatest date in my base dataset
something like : where date ge max date of base dateset !
Many thanks in advance :-)

1.First load your new file to a dataset 2.proc sql; select max(date) into :max_date from old_table; quit; 3. Now you can filter the date if the date is greater than the macro variable:max_date 4.you can append to the existing dataset.
