Analyse scores using time periods from a custom business calendar instead of only the standard
calendar.
When you are creating an Indicator Source, you can select either the standard calendar or a business
calendar defined on the instance.
If you use a business calendar, you can create data collection jobs that run on the Business Calendar:
Entry start or Business Calendar: Entry end times.
If you select a business calendar, you have the Calendar Frequency field. This field is required. The
business calendar you selected determines the range of available frequencies.
(Optional) If you have configured this indicator source to use a business calendar, set the number of
periods to retain scores and snapshots and find seasonal patterns.
