Change the fiscal year end to specify the end of the fiscal year in models.
Changing the fiscal year end results in partial years at the beginning and end of the entity. Partial-year data is discarded during conversion. To retain the data, add a year at the end and/or beginning of the entity.
To retain historical and forecast data in the years, define the years before and after the historical boundary in monthly detail
To ensure accuracy for years containing aggregate values like year-to-date or trailing periods, make sure there is enough time detail in each year, remembering that there is a 255 period limit. You use Entity Change Manager to modify time detail.
