Bonus Depreciation

Hi,

We have a requirement for having just the Bonus Depreciation in the 1st year and different rates in the subsequent year, So for example,

	1st Year	2nd Year			DPIS	JUNE
Cost	Bonus	Rate			SHOULD BE
					Year 1	Year 2	Year 3
10000	25%	30%		Depreciation	2500	2250	1575
				NBV	7500	5250	3675

In the Year 1, depreciation should be 25% i.e 2500, Year 2, it should be 30% of the NBV, which is 5250 and so on.

While I am setting the Bonus depreciation, it also calcuates the regualr depreciation in the 1st year.

Any ways to achieve this?

Thanks!
