Ledger Calendars

Hi,
 
We want to end our fiscal year in September 2025 instead of December 2025, but the fiscal year
was already created through December 2025.
Dynamics gives a duplicate month error message when setting up a new fiscal year from October 2025
through September 2026. What would a workaround be? Dynamics see October, November, and
December in 2025 as duplicate months.  There are already transactions in October through December 2025.  Please see attachment for error messages.  Thank you!
 
Regards,
Tricia Grams

    Hi Tricia,
     
    I have gone through your word document. 
     
    Solution would be: 
     
    To create a new calendar that will have all the periods available in previous calendar. With split of months 
     
    Assuming that transactions exists in Jan-24 period as well, need to create new calendar with all the existing periods as well.
    Old       New    
                 
    FISCAL       FISCAL-INC  
    Year1 Jan-24 Dec-24   Year1 Jan-24 Dec-24
    Year2 Jan-25 Dec-25   Year2 Jan-25 Sep-25
    Year3 Jan-26 Dec-26   Year3 Oct-25 Sep-26
            Year4 Oct-26 Sep-27
                 
     
    After updating this new calendar in Ledger setup. Click on "Recalculate Ledger Periods" on Ledger form, it will resolve your problem. Then it will start reflecting in Ledger calendar as well.

    hi
     
    fiscal years are controlled by accounting periods, and because you already created periods through December 2025, the system sees October–December 2025 as duplicates when you try to start a new fiscal year in October. The workaround is to shorten the existing fiscal year so it ends in September 2025 and then create a new fiscal year from October 2025 through September 2026. If transactions have already been posted in October–December 2025, those periods cannot be deleted, so in that case you will need to finish the fiscal year in December 2025 and then create a one-time short fiscal year from January to September 2026, after which you can move forward with the desired October–September cycle.
