One Asset class with Multiple Depreciation key

Hi,

I have one requirment in One asset class with mutiple depreciation key.

Asset Class :- Furniture & Fixtures

Aseet No :- 10000 - Depreciation Key 0001 - 10% Rate.

Asset No :- 10001 - Depreciation key  0002 - 5 % Rate.

- In OAYZ , Assign only one asset class with one depreciation.But AS01 asset master data user not change the depreciation key. Its posiable ?

Thanks
