Preventive maintenance next due dates
The next due date of a preventive maintenance (PM) record is the date it is next scheduled to generate a work order.
Due dates apply to any PMs that have the Use Frequency Criteria check box selected.
The next due date is determined by comparing values in the Estimated Next Due Date field on the Frequency tab of a PM, and the using the earliest date.
Other frequency criteria such as lead time, seasonal dates, and extended dates can affect when a PM generates a work order. For example, if a due date falls outside of the seasonal dates, the system finds the earliest date that falls in the active season and generates the work order for that date instead.
In addition, if the PM is part of a hierarchy, it can generate a work order because another PM in the hierarchy is due and it triggers all PMs in the hierarchy to generate work orders.
Example: Next due date for an oil change
A PM for an oil change is both time-based and meter-based. It is scheduled to generate a work order every 3,000 miles or three months, whichever comes first. The estimated next due date on the Time Based Frequency subtab might be January 30, based on average time elapsed between previous oil changes. The estimated next due date on the Meter Based Frequency subtab might be January 15, based on average mileage. The next due date for this PM would be January 15, the earlier of the two dates.
