The Admin at Universal Containers (UC) has created one bundle that contains all of its products as Options. The bundle has Subscription Pricing and Asset Conversion set to null on its Product record. Implementing the Product Catalog via a bundle allows UC to enforce logic about which Products can be sold together. A bundle sold by UC contains a combination of Assets and Subscriptions.

After making selections within the bundle, a sales user saves the Quote and creates a Contract from the Opportunity associated with the primary Quote. Later, the sales user needs to amend this Contract based on new requirements from the customer. When UC amends the Contract using the Amend button, the sales user notices that the bundle is excluded in the Amendment Quote.

Why is bundle excluded in the Amendment Quote?
