# Formula Fields ## Formula Fields in Salesforce Formula fields in Salesforce are **read-only fields** whose values are dynamically calculated based on other fields, expressions, or functions.\ Because their values are derived rather than stored, they might not always trigger standard change events when the underlying data changes. *** ### Syncing Formula Fields with Stacksync Stacksync can **synchronize formula fields** at a custom frequency that you define.\ This ensures that even though formula fields don’t emit direct change notifications, their computed values remain up-to-date in your destination system. #### How It Works * Formula fields are detected automatically during setup. * You can configure a **full table scan** for specific tables containing formula fields. * Stacksync will recheck and update those formula field values at the chosen frequency (e.g., every 24 hours).
