Minimum order quantity in DP

Hi Gurus,

Please help me with this issue..

We have only DP in APO and there are many SKUs with Min Order Qty(MOQ)..In DP when a planner enters the forecast in the planning book, is it possible for the system to popup a warning when the MOQ is not adhered..Example say the MOQ is 15 and if the planner enters a forecast of 8 units it should warn to add 7 more..

MOQ is a navigation attribute for the char 'Product'..may be a macro will do but how to?
