One of client has below requirement.
For easy stock movement and selling purposes they keep some items as 12 piece pack. During their sales operations, sometimes they sell the items as 12 piece packs as well as individual pieces. They have some scenario where they provide 1 individual piece as a free item when selling 12 piece pack. they are not keeping seperate item stock to provide as free item and they take individual units from 12 packs. How can we handle this.
