Unless you override the List Price, the price of the asset depends on the values you enter for defined the Price List Item fields under the Tax and Billing tab. Before you make changes to an asset, consider the pricing settings done on the product PLI. For more information, see "Defining Tax and Billing for Products" in CPQ on Salesforce Administrator Guide.

If you select the Is Asset Pricing checkbox on the Proposal Line Item detail page, when you Renew, Swap, Change, or Terminate the asset, Apttus CPQ accounts for any list price overrides on the original order to compute the price of the asset.
