Global order promising: Scheduling issue

Content

Hi,

How to setup Global order Promising so that it reserves order automatically only on Schedule ship date.

 

My current GOP setup reserves order without considering it, So an order that is created first and that has Schedule ship date after 4 days from now gets material reserved and same item becomes unavailable for other orders created after it with schedule ship date of today, as the item already reserved on previous orders

 

Thanks and Regards
