It is a legal requirement in Japan to round the depreciation percentage rates to three decimal places. There is a special control field, which enables you to control the internal determination of the depreciation percentage rates. You maintain this field in FI-AA Customizing (Valuation ® Valuation Methods ® Maintain Depreciation Key).

You can also define depreciation keys for the special declining-balance depreciation methods used in Japan. For more information, see Declining-Balance Method According to Japanese Requirements.
