How do I
a) add an addition to an asset that is fully depreciated/almost fully depreciated, so it does not adjust the cost of the asset used in depreciation calculation
b) run a proposal for depreciation for the asset and get it to calculate the depreciation correctly, just using the cost of the addition only and or what is left of the existing asset
I have tried to use acquisition adjustment journal for additions, but this adds the addition to the cost and depreciation is calculated using the new total costs.
