With the Multiple Calendars feature enabled, you can have more than one fiscal calendar to roll up accounting periods for reporting purposes.
The dates for the report range selected are based on the accounting period rollup in the context of the fiscal calendar assigned to the subsidiary.
For consolidated reporting, when you run reports for a single subsidiary, the associated fiscal calendar applies. When you run a report at the consolidated level, the fiscal calendar associated with the highest-level consolidated subsidiary determines the accounting period hierarchy.
