Hello, I'm trying to build quantity system and i want to hide the items if the item quantity is 0
i have add column in items table which name quantity, so if the quantity is 0 i want to hide this item from user app how can i do that and wich file i have to edit
I know that i need the extended license if i want to edit user app but this operation has a relation with database so i want somthing with logic
Thank you
