How to change physical year calendar

AI generated answer (using internal Slack threads):

To change the fiscal year calendar in NetSuite, you can follow these steps: 1. Navigate to Setup > Company > Fiscal Calendar. 2. Click on the 'Edit' button. 3. Modify the 'Start Month of Fiscal Year' to the desired month. 4. Click on 'Save'. However, changing the fiscal year will not preserve the reporting from previous years to match the new fiscal year. If you want to report prior fiscal years using their old fiscal year, you might need to customize your reports. If you are changing the structure of your accounting periods, such as closing on the last Saturday of every month, you can modify your accounting periods to match this. However, changing dates on periods needs to be done carefully as the system may not save the changes if not done correctly. If you encounter any issues, you could consider using the Multi-Calendar feature if you have it. You can build a new calendar the way you want it and then switch your subsidiary to use the new calendar. It's recommended to test these changes in a Sandbox environment before implementing them in production. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
