The Admin at Universal Containers is receiving an "Attempt to de-reference a null object" error when generating a Quote Document after adding the following section to display line items with the Product Family Setup Fees: What change needs to be made to resolve this error?

Universal Containers wants to provide a 10% discount to Product A, but only when customers who have previously purchased at least one unit of Product A decide to purchase more. The CPQ admin has set up a price rule, but it is currently running on all lines that contain Product A.
Product A is a subscription product.How should the CPQ admin prevent this rule from firing when a customer first purchases Product A?

Given the Discount Schedule and pricing details of the Cloud Storage Product, what is the calculated Regular Unit Price for the Quote Line?
Quote line field values:
*List price: $100
*Quantity: 5
Discount Schedule field values:
*Type: Slab
*Discount Unit: Percent

Universal Containers needs to generate two styles of PDF output, one that includes prices in the line item table if the Quote is another that hides prices when the Quote Primary checkbox is False.
Where should the admin reference the Primary checkbox field to set up this requirement?

Universal Containers (UC) has a Product family called Software. When a Configuration Attribute in the bundle is set to Perpetual, UC wants to Hide all Products with the Product Family called Software. The Admin has created a Product Rule with a Configuration Rule.
Which additional supporting records should the Admin configure so the Product Rule meets this requirement?
