[Error] - I can sell more than I have in stock

[PauloRobert]

Currently the system is allowing to sell more than the amount I have in stock.
I registered 4 products, but sold 5 and the stock was negative.

Where can I get this function so that inventory is updated whenever there is a sale and does not allow me to sell more than I have in stock?
