TOPIC: Item location

Inventory stock can be managed manually and automated. Order processing and purchasing automatically updates sold and purchased stock, and picking and moving forms do the same. Then there are two ways where stock can be updated manually, through product details under the inventory menu and then product, or on warehouse level, also under the inventory menu.

I have three locations. When entering a new product, how do I initially assign product location and existing number of items? After I entered product number, it seems I must go to "Warehouse locations and do an initial inventory count? or I'm not understanding.
