Full depreciation if the asset is purchased with in first 15 days of the month

Hello All,

We have requirement in Asset accoutning.

If the asset is purchased from 1st to 15th of a month, the depreciation should be charged for entire 1 month.

If the asset is purchased between 16th to 31st of a month, then only half a month depreciation shjould be charged.

Could any share how this can be done in SAP - Asset Accoutning?

Regards,

MG
