How Depreciation Adjustment Amount can be calculated?

Hi,

We are managing a book and currently focusing on the period of Apr-24 (considering 12 periods in the current year). We need to migrate some assets and calculate the depreciation amounts. Specifically, for Apr-24, we need to determine the depreciation amount for the month of Apr-24 and the adjusted depreciation amount for the previous months (Jan, Feb, and Mar 24).

We have the depreciation reserve until Dec-23. However, when we attempted to calculate the depreciation, the adjusted depreciation amount was not computed correctly.

Could you please advise on the correct procedure to calculate the previous periods' depreciation?

Thank you.
