Adjusting an existing asset from PO Receipt

Should an adjustment through integration with PO/AP to an asset currently in the repository update the description, serial number, etc? For example, when new hardware cards are purchased for an existing server, and the asset ID is entered on the receipt, transactions are generated that update the description of the server, change it's serial number, and even update the acquisition date.  This wreaks havoc with our inventory processors who rely on the assets description and serial numbers. This happens every time the user enters an existing Asset ID on the receiver.
