Hi,
Imagine you have a big storage with 5000 items, to search for an item in such warehouse you will need hours to find it.
BUT, if your warehouse is organized in racks, and each item is located under a specific rack, you can simply pick us 10 diffirent items in less than 10 minutes as you know exactly where is each item located in that warehouse.
If you need it i can guide you how to setup racks.
