When creating a Purchase Order from one or more Purchase Requisitions, you now have the option to purchase a quantity less than what was initially requested in the Purchase Order Preview window.  The remaining quantity on the Requisition will then be canceled.  

For example, if you have 70 quantity of the item 128 SDRAM on a requisition, but you only want to purchase 35 of those items, you can now adjust that quantity in the Purchase Order Preview window.  

When adjusting the Qty To Purchase field to 35, you will receive a warning stating "The remaining quantity ordered will be cancelled". 
 

When generating the Purchase Order, the Purchase Requisition will move to history if all lines on the Requisition have been fully or partially ordered with the remaining quantity on the partially ordered lines cancelled.
