Hello, 

Is it possible to disable sales back orders then enable it later in future ?

Example: When a customer ask for 10 pieces of a product and we only have 5 available, my employees create the sales order for 10 and we get 5 as back order, I just wanna disable that so my employees will not be able to create a sales order if we're short on items in inventory (sales order quantity is more than inventory), that will be for a while until I go with best practices for back orders and forcasting.
