Freedom has the ability to group multiple SKUs, or items, together to sell under a single SKU. This is referred to as a Group Item.
If the inventory group tax category is set to a different tax category than the individual items in that group, the inventory group tax category takes precedence.
In the Inventory Department, navigate to the item that will contain the group items.
On Item Dashboard, select the Pencil on the Group Items widget to edit.
There are additional weight and stock override options:
Parent Item Weight Override - When populated, the defined weight will override the weight of the entire group.
Parent Item Stock Override - If enabled, only the parent inventory Out of Stock/Low Stock conditions will be checked. If left disabled, all child inventory will be checked for Low Stock/Out of Stock conditions.
Following these steps will result in successfuly adding group items to a single item.
