Field help (FIRFIYFLG) 

This indicator must be activated if the acquisition fiscal year must be counted as a full year during the definition of the depreciation end date.
This information is useful when the asset depreciation start date is later the the fiscal year start date.
For instance: an asset is acquired on 03/01/2005 and depreciable over a period of 3 years.
- If the indicator is activated, the depreciation end date will be 12/31/2007.
- If the indicator is deactivated, the depreciation end date will be 02/29/2008.
