Product Creation Issues Magento 2.3 (Backorders Off but QTY still goes below 0)

[dvlptechno8a58]

Hello Everyone,

We're encountering an issue wherein if products are set to No Backorders but people can still order beyond their allowed quantity.

Global settings are:

Managed Stock -> Yes

Decrease Stock on order

Backorders: No Backorders

Product Level:

Managed Stock -> Yes

Out of Stock Treshold -> 0

Backorders: No Backorders

What's more odd is it is happening intermittently. For example, we create 3 products and everything will work fine. The next 3-4 products that we will create will have the issue and they can't be repaired at all and the only way is to recreate them from scratch. Using the duplicate button will carry over the issue.

Any thoughts on how to tackle this?

Hi @dvlptechno8a58 

All configuration you have shared are correct. 
After set backorder No then it will never go to out of stock status.

If you are set backorder and product is already out of stock then it will not work, so you need to change product out of stock as well and save products again.

Also run below command after set all configuration:

php bin/magento indexer:reindex
php bin/magento cache:flush
