I have set Stock management Yes but My website have only three option, i cant put Qty of product. Please help me. My magento version is 1.9.3
Configurable product do not have the Quantity
field. They are not physical products, so they can't have exact qty amount.
If all associated products of a configurable product are out of stock, then configurable product itself is considered out of stock.
Further more, under System -> Config -> Catalog -> Inventory
, you can choose if Magento show render out of stock products on the frontend. Maybe this is something that you actually want?
