Depreciation Override and Amortization effect

We have the following scenario:

Asset Value: 3600

DPIS: 27-FEB-2011

Life: 3 Yrs

Financial Year: Feb to Mar (first day is Feb 27th and Last day is Mar 3rd 2011) FY12

After first year the depreciation is 1200 which is right.

In Period 1 of FY13 (Mar4th).. FY13 Financial year is Mar 4th to Jan 2013-- we have 336 days in FY13 (I know we have less days, but that is not an issue)

For Period 1 we do not want to depreciate so we use the Depreciation Override functionality so we insert a '0' depreciation using the override screen

For Period 1, the depreciation is calculate zero..this is good. So the remaining life as of this time is 23 Mths
