Post test data in the form of a datastep for next time, follow:

https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-data-AKA-generate/ta-p/258712

You code should look something like:

data want;
  set have;
  years=intck('year','31MAR2014'd,couponexpiry);
run;

Adding a bit to @RW9

Your couponexpiry date variable would have to be a SAS date valued numeric. If your current value is character you will need to create a date value using input(couponexpiry,ddmmyy10.) before any calculations.

And the literal date used, '31MAR2014'd has to be in that form. You cannot use '31/04/2014' or 04/31/2014' or someother data appearance. It must be as displayed by either the SAS Date9. or Date7. format when using a literal value.
