When you click PM by Class Code from the Setup/Inventory menu, the system displays the PM by Class Code window. Use this window to establish preventive maintenance (PM) activities for a type of equipment ("class code"), and when those activities are scheduled.
There are two ways to define PM schedules:
- By inheriting PM activities from the nearest class code ancestor that has a set of PM activities assigned to it.
- By directly entering the set of PM activities, which takes precedence over inheritance.
