In MD, I recommend having the "Target Start Date" populate with the current date when duplicating work orders.
For example, once a month, I create a group of work orders for one of our departments. Each work order I duplicate is for the current month. When I duplicate the work order, it populates with the last month's target start date. When I use the duplicate work order function, I find that I am creating it for a current problem, and don't need to back-date it.
