We have a major problem with Magento 2 where the stock of items get decreased by itself without orders being placed.
Can anyone tell me when stock decreasing occurs in Magento 2?
Does it happen when quotes are added to the database? Does it only happen on order success?
Does it happen on order failures?
Something is not right and this is causing us major problems with incorrect stock quantities.
We do not use MSI, but the default inventory system.
According to Magento documents, stock decrease only when customer placed order.
Configuration for set from admin as showing within below image:
