Calculation of Depreciation Amount is not coonsidering existing depreciation amount if there is Revaluation entry on FA Transactions

Dear Support,

I have a scenarion below:

Service life for the asset is 48 months.

when i calculate depreciation using Depreciation proposal, the amount of depreciation calculated is 322,916 that comes from 15,500,000/48.

I think the correct based amount for calculate depreciation is 15,000,000 instead of 15,500,000 because Net book value is 15,000,000.

any could tell me whether this is a bug?

Thanks,

Yohana
