Hi,

WH/Input and WH/Stock are both internal locations in a warehouse. However, they have different purposes.

WH/Input is a location where products are received from suppliers. It is typically used to store products that have not yet been checked for quality or that are waiting to be put away in their final location.

WH/Stock is a location where products are stored after they have been checked for quality and put away in their final location. It is the main location where products are kept in a warehouse.

Hope it helps
