Hi John,
A work order with Recurrence type = Series will not show up on the calendar. Only Occurrences and One Time recurrence would show. The reason for this is that a series is a holder of all general occurrence information, but it not an appointment itself.
So to paint a picture so you understand how to input the work orders. If you are creating a daily Recurrence for 3 days starting today, then you must input the start date as June 17th and end date June 19th. That way the 3 work orders that are created would have Recurrence type = Occurrence. Please let me know if this helps.
