Zero value Depreciation

Hi

Can we post the Zero value depreciation also. Since i have assiged '0000' depreciation key to some of assets. Those assets are prediacttly calucullated the Zero value depreciation. After one year i have change the depreciation rate from 0000 (O%) to C400 (5%) . This i want to run the depreciation. But was not allowing to run the depreciation . Becuase of last year i does not posted any any depreciation. Even assets value also i should be posted in the assets. Then only i can run the depreciation for the year.

Please suggest me how can i post the Zero value depreciation for the last year.

Thx

Ram
