I already created a calculated column called Reminder in my custom list that calculates the date 72 hours later after the item is created (ex. Item created 6/13/2016, Reminder column shows 6/16/2016). I have 3 stages (divided by department) in a workflow, what condition/action can I add in each stage that sends a reminder to that department that there's an item idle for more than 72 hours? I want them to get that reminder only once.
Thanks in advance!
