Fixed Asset Depreciation

https://frappe.github.io/erpnext/user/manual/en/accounts/managing-fixed-assets

@felix thanks for your help, but in the country am working with there rule for fixed asset depreciation is by percentage like
for vehicles 10% every year with double declining method and supposed it will be finished in 10 years
for computers 25% every year with double declining method and supposed it will be finished in 4 years
so how can we manage this kind of issues ?
thanks!
