In Fixed Assets, if you are using a variable Fiscal year in Fiscal Period setup and you base your Fixed Asset calendar from the Fiscal Period Calendar, you must rebuild your Fixed Asset Calendar for all years every year. When building the Fixed Asset Calendar it will look to the Fiscal Period Setup for any years that are available and then copy the most recent year to the future years in the FA Calendar which could cause discrepancies between the Fiscal Calendar and the FA Calendar. To rebuild the calendar, Go to Tools>>Setup>>Fixed Assets>>Calendar. Mark the Build Calendar check box, choose Fiscal Period Setup, leave the years as defaulted and choose Build Calendar.
