One calendar per company
A fiscal calendar belongs to a legal entity, not to the organisation as a whole — a group with more than one company can run a fiscal year starting in April for one and January for another. Each calendar has:Generating periods
A calendar with no periods cannot be used — nothing can post into a year that has not been broken into periods yet. Generate FY<year> builds this year’s and next year’s periods from the calendar’s own settings, and you generate the next year again each time one is needed rather than generating far in advance.Closing a period
Each period steps forward through three states:
A month closes when everything that posts against it has — which is why the calendar sits apart
from any one book: a budget, a capex plan, and a depreciation book can all be counted against the
same fiscal year, and the day they disagree about when April starts is a reconciliation nobody
wins.
Where this is used
This is the one piece of financial setup that does not belong to any single module. Whichever of these your organisation has, they all read the same calendar:- Budgets — see budgets
- Capex plans
- Depreciation books
