maximumExecutionFrequency

The frequency at which you want CC to run evaluations for a custom rule with a periodic trigger. If you specify a value for `MaximumExecutionFrequency`, then `MessageType` must use the `ScheduledNotification` value. By default, rules with a periodic trigger are evaluated every 24 hours. To change the frequency, specify a valid value for the `MaximumExecutionFrequency` parameter. Based on the valid value you choose, CC runs evaluations once for each valid value. For example, if you choose `Three_Hours`, CC runs evaluations once every three hours. In this case, `Three_Hours` is the frequency of this rule.
