Written Down Value is ( WDV ) justified with a notion that some of the assets are more efficient in the earlier year of their life. As the depreciation is calculated each year the amount is deducted from that year’s asset value to calculate the asset value for the next year.

That means, it is charged on the reduced balance of asset. SAP has some standard delivered Written Down Value method ( WDV ) depreciation key which calculates depreciation for the Asset assigned to the asset class attached to the Written Down Value ( WDV ) depreciation key.
