When viewing the order page, you may ask what the difference is between a Locked Warehouse and an Allocated Warehouse. This appears when you have multiple warehouses in which you ship products out.
Locked Warehouse Vs Allocated Warehouse
The Locked Warehouse option is visible on accounts or client accounts with Multi Warehouse Allocation disabled. A Locked Warehouse refers to the warehouse where the order should be allocated. If two or more warehouses exist and the order is pending, you can manually select a different warehouse from the drop-down.
An Allocated Warehouse refers to the warehouse where the order is allocated. Accounts with Multi Warehouse Allocation enabled will only see this column within the order details, and manually selecting a different warehouse is unavailable since MWA rules determine the allocated warehouse.
