Universal Containers allows clients to negotiate a discount for Product A until a specified date up contract activation. Which three fields on the Contracted Price record should be configured to satisfy this requirement?

A user needs to amend a contract and change prices to reflect new discounts for existing active subscriptions and assets.
How should the user achieve this?

A Quote has one Quote Line for a subscription product with an End Date that differs from the Quote's End Date.
Which date will CPQ use to calculate the prorate multiplier?

Universal Containers has a bundle with many Features. In one of these Features, Feature A, all Product Options share the same Discount Schedule.
How should the Admin set up a Discount Schedule so the quantities of all Product Options in Feature A are aggregated when determining the Discount Tier?

The Admin at Universal Containers recently created a new custom field referenced on the Target Field on a Price Action in a Price Rule. While testing the Price Rule, the Admin noticed that the Price Action failed to populate the custom field. The Admin checked the CPQ Package Setting and noticed that the Triggers Disabled checkbox was checked. After unchecking Triggers Disabled, the custom field still failed to populate.
How can the Admin ensure this custom field can be referenced by the calculator?
