I have a list with recurring actions that must be completed at different intervals; 7 days, 36 months, 12 months etc.
How do I create a workflow to send out recurring tasks or notifications on the due date
I am not aware of a direct way of setting up a recurring tasks in Nintex, but you could achieve it in a variety of ways depending on your requirement.
1] Create a task in a loop (which can loop depending on the interval you need
Pros - This could a genuine recurring tasks which wont have an exit (unless you specify a specific exit condition)
Cons - if the first task is not responded, then the task will not move ahead to the next recurring task. i.e. if 7 day task is not completed then the 36 month task will not be triggered as its sequential. (This also could be circumvented by creating this in a parallel task and exiting after a certain time only using request approval not flexi task)
2] Create parallel task for each of this 7 days/36 months etc.
Pros - Task would be generated when the time comes and it will not be depended on the earlier task to finish
cons - We need to know before hand how many recurring tasks you need.
