Work with fiscal year settings
Getting to app feature settings can vary based on the type of app (Unified Interface or the legacy web client) you're using. You might need to adjust the procedural steps in this topic to reflect your app type. See Settings.
Also, we are moving some settings from model-driven apps in Dynamics 365, such as Dynamics 365 Sales and Customer Service, and the Dynamics 365 Admin center to the Power Platform Admin center. See Environment settings are moving.
You can set the fiscal year period, and how it’s displayed, for your organization.
After you set the fiscal year options, you can’t change them. Fiscal year options affect the way in which your organization's data is stored in model-driven apps in Dynamics 365, such as Dynamics 365 Sales and Customer Service.
Make sure you have the System Administrator security role or equivalent permissions in Microsoft Dynamics 365.
