Maintenance schedules can be based on either duration or meter and can be triggered by the
first occurring related condition. For example, on the Maintenance Schedule form, select
Duration or Meter as the trigger for an automobile maintenance
schedule and then define the duration as three months and the meter as 5,000 miles. The
schedule is triggered by whichever comes first.
With the Duration or Meter trigger selected, the Next run
time and Next run value fields are populated in the
Maintenance Plan Records related list on the Maintenance Plan form.
See Define a maintenance schedule for more information.
