Capitalization & 180 days

Hi Friends,

I have configured the all asset accounting.Suppose when I am purchasing asset on 01.11.2008.System shuld be calculated on purchasing date. but when I am seeing in Aw01n asset explorer in Posted Values tab, system showing all the year depreciation divided into period wise. But my client requirement is it should be from 01.11.2008 to 31.03.2009.

The another thing is in asset accounting 180 days. If suppose we are using asset below 180 days, the depreciation is half year.If more than 180 days dep is full year.

So can any body plz help me out for above two issues.Reply will appreciated with points.

Thanks

Amar
