This interface allows you to manage available quantities for sale for products. It also allows you to manage product combinations in the current shop.
You can choose whether or not to use the advanced stock management system for this product.
You can manually specify the quantities for the product/each product combination, or you can choose to automatically determine these quantities based on your stock (if advanced stock management is activated).
In this case, quantities correspond to the real-stock quantities in the warehouses connected with the current shop, or current group of shops.
For packs: If it has products that use advanced stock management, you have to specify a common warehouse for these products in the pack.
Also, please note that when a product has combinations, its default combination will be used in stock movements.
