Time phased inventory cost changes

How are other MAPICS users addressing the need for keeping up with vendor
cost changes in a proactive manner?
   Can you point me to a package/solution that will provide us an option to
      pre-load future cost changes with an effective date?
   (We have both one-at-a-time changes as well as mass loads for 2000 item
      cost changes from a single vendor.)

   Also, we need to take into account the impact on inventory and new
      purchase orders.  Ideally we would start buying under a new price in
      advance of updating the inventory cost.  (This may be asking too
      much!)  The possiblity of loading the purchase price field in advance
      of loading the unit cost default and the current cost fields.

   Thoughts?  Suggestions?

   THANKS
