If you have specified a recurring schedule for the measurement, then this field indicates the expected status of the job at the time the measurement is scheduled.
In the case of a single occurrence of a batch job, use this when the exact time the job will be executed is unknown or varies. Measurements that have a future schedule associated with the job will accommodate an interval of up to 999 minutes only. Measurements for a single occurrence of a job (i.e., no future schedule) will accommodate an interval of either 999 minutes, 22 days or 3 weeks.
