About this chapter
What this chapter covers
Business Logic and Process Automation is 32%, the largest section of the Salesforce Certified Platform App Builder exam. It covers formula fields, roll-up summary fields, validation rules, building flows in Flow Builder, Flow approval processes, choosing a flow type, maintaining and troubleshooting flows, and Agentforce automation capabilities.
Questions are mostly scenarios: a company has a requirement, and you choose the declarative feature or setting that meets it. Writing code is the expected answer only when declarative tools cannot meet the requirement.
How the topics fit together
Business logic calculates values, checks data and automates processes. Formulas and roll-ups calculate, validation rules block bad data, flows change records and run actions, and agents call flows as actions.
Match the tool to the job: a value derived from the record is a formula, a total of children is a roll-up summary, blocking bad data is a validation rule, and changing records is Flow.
