#468

Short Description and Why It's Useful

• Added support to fetch the updated inventory of the item in the order.
• It only runs when the user has already checked the QOH on any of the tabs from "Open" and "Packed."
• If the user directly checks the inventory on the "Completed" tab, it will show the updated inventory of the item.
