I have an existing asset that was capitalised 01.Nov.2023 with a 2 year useful life, say for example with an original value of 1.000 ,

in such cases, you might use a depreciation key which uses base method 'depreciation from useful life', base value `24 net book value' over remaining useful life.

Besides, all acquisition postings in the acquisition year are depreciation from depreciation start date, irrespective of the value date.
