How Accounting Calendars Are Validated

Calendar validation is automatic and prevents serious problems when you begin using a calendar. Once you set a calendar period status to open or future enterable, you can't edit the period.

Settings That Affect Calendar Validation

Calendar validation runs automatically after you save the calendar.
