Next Work Order Only Flag - What was the intended business case?

Summary:

When setting up a PM Work Requirement, there is an option "Next Work Order Only". When work order is completed, it creates the next work order.

Question is, what is the expected behaviour if the trade person cancels the work order instead of completing the PM Schedule (ie skipped for some reason)

Currently it appears to never re-schedule, so fails in a dangerous state.

Content (required):

If you define a PM schedule using the Next Work Order Only Flag, the program generates only the next work order once the previous one has been completed.

Currently if you cancel the work order, the schedule doesn't take this into account and re-schedule the next work order. It just stops occurring?
