An Event Trigger activates a PM Plan when the number of service requests for an asset exceeds a threshold number in a specified time period. This trigger is useful for activating a higher level PM plan when a certain number of routine PM plans have taken place. For example, this trigger could activate a complete overhaul.
Currently, the only event supported is the number of service requests in a specified period.
