You may have a number of products such as Hampers, Subscriptions or Gift sets that are made up of many other products.
If this is the case, all the products in the Set should be created as individual products and then linked to the parent product ie the Subscription as Included Products.
The Subscription should also be created as a separate product (the parent record).
The Included Products sublist on the Products form can be used to itemise products that are part of the parent product.
If a Subscription contains several issues, all of these issues would need to be linked as Included Products in the sublist of the Products form.
The Included Products sublist also manages the quantity of the included issues/products to be included.
