Hmm, I don't think it has anything to do with the specified revision.
Let's look at the product example
https://crm.hotsalon.com.ua/admin/shop/products/610/storage/:- quantity 1
- reserve 1
If you look at the minimum reserves
https://crm.hotsalon.com.ua/admin/shop/storage/report/reserve/?categoryid=0&... D1% 8C% D1% 82% D1% 80% D0% BE% D0% B2% D0% B0% D1% 82% D1% 8C - the situation is the same
And it turns out, according to the logic of the action, that if there is more goods in stock than in the reserve, then it does not need to be re-ordered.
Perhaps some similar situation was not taken into account in the revision - indicate how, in your opinion, it should work?
