editent Posted January 31, 2014 Share Posted January 31, 2014 Hey guys, I'm using just the simple quantity management, not the advanced stock management. I have a product with three combinations (Shirts Sizes S, M, L) In the tab quantities I used "I want to specify available quantities manually." and gave each combination a quantity of 100. When out of stock is set to Deny orders. A lot of shirts are sold and now I have a quantity of -1 in size M and L. In S are still 12 available. How is it possible to get negative values? In the frontoffice it is not possible to order M and L or more then 12 S. Could it be because some orders where canceled? But shouldn that refill the quantities? Or is it possible that two persons buy the last shirt at the same time? Greetings editent Link to comment Share on other sites More sharing options...

zolwix Posted July 19, 2016 Share Posted July 19, 2016 I have this problem too on Prestashop 1.5.6.2, why is this happen? Link to comment Share on other sites More sharing options...
tanasi Posted August 5, 2016 Share Posted August 5, 2016 I have the same problem in 1.6.1.1 with simple quantity management. A lucky guess will be that it occurs when two people buy the same product at the same time. So maybe it is related with this: http://forge.prestashop.com/browse/PSCFV-9970 Link to comment Share on other sites More sharing options...
