Currently there is not an effective way to say that specific inventory should not be available for picking unless you restrict availability to only one location and transfer stock to a separate quarantine zone. This is very cumbersome.
1) If batch tracking is available for an item you can select a batch and say whether that batch is available for picking or not.
2) If no batch tracking you can also say a particular zone in a location can be specified as locked for picking. This implies that you can transfer items between zones or bins.
Functionality such as this is available in many competitor inventory management or ERP products.
