FA Depreciation- Need help on formula to make NBV=0

Hello

I am working on asset module and below is the information for the asset -

Please refer the attachment for Depreciation information . .

When depreciation is calculated for FY 2019 gives desire result. .

But when I tried to execute depreciation for Period 6 FY 2020 I am interacting with below error

- Error 084Y - Over Depreciation is not allowed.

Further, when Rule Convention change to 1 then system calculates depreciation which is more than the asset cost.

My expectation is system should calculate depreciation 146.45 which will make NBV=0

(443.79-297.34=146.45)

Can you please help me with the formula to be used to get desire result. . .

Thanks in advance
