In the situation where you have searched a specific bin and want to take out the item(s) from this bin, you might get a warning asking 'Are you sure you want to remove items?':
Removing the allocated stock
As the message explains, the product in this bin (or shelf location) is already reserved for an order. If you decide to proceed and 'Confirm' that the allocated products are removed, the order with this product will change its status to 'Open'. It will also be listed on the Dashboard as an 'Out of stock'-order.
Restocking the product
As soon as the product comes back in stock again (it can be stored in a new bin or shelf location), the Out-of-stock order will be allocated the new inventory and move to status 'In Progress'.
