How to set up depreciation beyond useful life for asset

Summary:

How can I enable the option to allow oracle FA to automatically depreciate an asset until a set depreciation limit, beyond set salvage value, and beyond set useful life as well. This is a requirement for Taiwan’s regulation.

Taiwan asset depreciation requirement:

For asset life=> Life of asset is based on each asset

Life of asset is not included the residual value

Residual value is 1 year =cost/ (useful life +1)

Depreciation = (cost-residual value)/useful life

Use case:

Asset Cost: $60

Useful life : 4 years (48 months)

Residual value = $60/(4+1)=$12

Depreciation = ($60-$12)/48 months = $1/per month

Depreciation in the fifth year is residual value/12 months =12/12=$1/per month
