How to prohibit the purchase of goods if the quantity of goods in stock is less than the customer wants?

Question

1C-Bitrix

Colleagues, good afternoon

Chet, I can not find the functionality. The site includes quantitative accounting and there is a ban on the purchase of goods, if zero or a negative quantity.

There are 25 items in stock. The customer entered 60 pieces in the cart and the order went through. How to prohibit skipping an order of 60 pieces, because there are 25 of them. Poke into the manual or somewhere else. Thank you!

Answer 1

1) Check the module.
Is quantification included? Is it allowed to buy in the absence of goods?
2) Check individual product settings (can be overridden for each product)
Is quantity accounting enabled? Is it allowed to buy in the absence of goods?
3) Check the actual amount available.
The quantity of goods in stock is not the quantity of goods. Bitrix displays this for reference only, the real quantity is taken from another field in the product card.
4) Check the checkout template.
Perhaps it is customized or written from 0. There may be no such mechanics in principle
