Japan Special Depreciation
If you are using the Japan Special Depreciation, you must enable Custom Transactions in your account. Go to Setup > Company > Enable Features > SuiteCloud. Under the SuiteGL section, check the Custom Transactions box.
Companies that meet the Japanese tax authority's requirements may apply a special depreciation to their assets. This method is an accelerated depreciation that's applied in addition to the asset's regular depreciation.
The special depreciation lets customers complete the depreciation process early and calculate their taxable income. Customers can apply the special depreciation to an asset within the first 3 years of its life.
The special depreciation can be applied only to assets that use the Japan Straight Line, Japan 200 Declining Balance, and Japan 250 Declining Balance methods.
