Universal Containers has three product families - Hardware, Software and Services.

 Salesforce Revenue Cloud’s CPQ (Configure, Price, Quote) solution allows for the creation of price rules that can be used to performcalculations on quote lines. In this scenario, the CPQ admin has created three separate price rules, each using a summary variable to add the net total for quote lines belonging to a particular product family. While this solution works, it may not be the most optimal from a performance standpoint.

Option D suggests using a single price rule with three price actions. This would be more efficient because it reduces the number of price rules that need to be evaluated. Each price rule evaluation can consume system resources and potentially slow down the quote calculation process. By consolidating the three price rules into a single one withmultiple actions, the system only needs to evaluate one rule, which can improve performance.

It’s important to note that summary variables in Salesforce CPQ allow you to perform a math function on the collected values of a number field on the quote line, product option, subscription, or asset1. You can also create filters so that the summary variableevaluates only fields on records that match the filter values1. This functionality would still be available with a single price rule with multiple actions.
