Addition Asset Depreciation to calculate from the first acquisition date

Hello All,

I have AUC asset first acquisition date/Value date is 01.01.2020 value 10000 and Addition value is 5000 value date is 05.05.2020.

My requirement is want to calculate the depreciation for addition asset from the first acquisition date onwords (01.01.2020). However, If i try to capitalize the full amount from AUC to Main asset with value date 01.01.2020 not allowing to post. So i have capitalized partially 10k value date 01.01.2020 and 5k value date 05.05.2020.

Based on the current configuration setup calculating details as below:

Used period control method 002 and 003.

Asset Acquisition AUC 01.01.2020 Value 10000

Asset AUC Addition on 05.05.2020 value 5000

Main asset capitalized on 01.01.2020 value 10000

Addition asset Capitalized to Main asset on 05.05.2020 value 5000

Depreciation (useful life 5 Years) Depreciation year 2020 value 2000

Depreciation (useful life 5 Years) Depreciation year 2020, 8 months value 714.286

Total depreciation year 2020 value 2714.286

Expected depreciation calculation

Depreciation (useful life 5 Years) Depreciation year 2020 value 2000

Depreciation (useful life 5 Years) Depreciation year 2020 value 1000

Total depreciation year 2020 value 3000

Can anybody help me on this?
