What does the differents statuses for an order mean - active, locked and permanently locked

Differents statuses explained

Active - The order is currently active and will be ready for delivery if all products are available in stock. 
 
Locked - If you are unable to deliver the order directly and it requires manual editing, such as when a product in the order is out of stock, you can choose the "locked" status. When an order is locked, it cannot be delivered and must be unlocked by crossing out the locked status and saving the order. All locked orders can be found under Administration -> Pending orders - Manual. The order will be temporarily locked.
 
Permanently locked - The order will be canceled, and this action cannot be reversed. It is possible to cancel the order if it cannot be delivered, for example, if the customer has regretted their order. However, this can only be done if the order has not already been delivered.
