In Japan, if there are assets for which you want to set the residual book value to 0 yen (intangible assets) and assets for which you want to set the residual book value to 1 yen (tangible asset) with Old straight-line or Old declining-balance method, even if they have the same depreciation method and accumulated depreciation limit, you will need to prepare separate book for each asset.

If we could maintain the residual value settings on the fixed asset group book level, the configuration would be easier and simpler.
