being "stolen" from one order for another this will be accomplished by setting the allocation date to today.

This will give the customer service representative an easy and efficient way to display the ATP for an item as it is
entered on a sales quotation or sales order. A GBS ATP Scheduling option will be added to give a quick way to
align dates for an entire order based on the available to promise quantities and based on the allow partial delivery
