Unreserve Delivery Order Items
If a DO has three items of stock, two in stock and one awaiting stock, how can I unreserve one of the available items to ship on another DO
Product A - 1 Ordered - 10 in stock - 1 reserved
Product B - 1 Ordered - 0 in stock - 0 reserved - 10 - due in 7 days
Product C - 1 ordered - 1 in stock - 1 reserved - 10 more due in 7 days
Product A - 1 ordered - 10 in stock - 1 reserved
Product C - 1 ordered - 1 in stock - 0 reserved
How can I take product C from DO 1 to fulfill DO 2 knowing that DO 1 will be fulfilled when all the on order stock items come in.
