In the example in the linked thread, the DateType field and set analysis are only required to handle the case where a single key field has more than one date field associated with it, and we want to preserve that information.
I see nothing wrong with your example, but it isn't designed to handle that case.
Thanks for your reply. I understood clearly by your explaination why my solution won't work when multiple dates are associated with single key field. We have to use date type in link table and set operator to distinguish between two dates.
