Reproducing the Issue
The setting is decided by o field "Aqc" in item "Period Control Methods", which can be displayed in APP "Depreciation Key:Display Details".
There is no way to change the setting of depreciation key. However, there is a depreciation key "SUL2", which 'Acq' setting is 02 "pro rata upto mid-period at period start date", that can meet the request.
