Inventory Value by Asset Class

Is there a place in IFS EE where the Asset class is stored with the Inventory Value?

  We use the inventory value by period to report our total inventory levels, but we would like it by Asset Class.  There are views in IFS that has the information, but the views seem to capture the data when the view is displayed hence the asset class displaying with the historical inventory value is the current asset class, not the asset class when the historical data was taken.
