Did you know that we added functionality to encumbrance?  Now there is a notification.

When you encumber an item in Purchase Order Entry, you reserve a certain amount of your budget for the item based on the item cost. 

With Microsoft Dynamics GP 2013 Encumbrance Management, if the receipt item cost is different than the original encumbered item cost, you will be warned that the costs are different.  This will help you reduce data entry errors and control costs.
