What is Guided Selling in CPQ and how does the Product Configurator work?

Guided Selling in CPQ presents a questionnaire-style wizard to sales reps that recommends products based on their answers. Configuration:

1. Process Input Records (SBQQ__ProcessInput__c): Define the questions (e.g., "What industry is the customer in?" or "How many users?"). Each input has a data type, label, and optional default value.
2. Process Input Conditions: Determine which follow-up questions appear based on prior answers (branching logic).
3. Product Recommendation Mapping: Process Input values are mapped to Product Filter criteria — the wizard filters the product catalog to show only the matching products. The rep selects from the recommended products and adds them to the quote. Product Configurator (the standard bundle configurator): Once a bundle product is added to the quote, the configurator opens showing features, options, and real-time pricing. Option constraints, product rules, and custom scripts all execute within the configurator. Guided Selling and the Product Configurator work together to reduce configuration errors and shorten the quoting cycle.
