> CaptionClass is a property that creates dynamic captions changing based on data or context, with dimension fields as a common example. It helps build flexible, context-aware captions using reference codeunits from the base application.

## Key points

- CaptionClass property enables dynamic captions that adapt based on data or setup context
- Dimension fields use CaptionClass to automatically update captions based on dimension configuration
- Seven codeunits in the base application implement CaptionClass as reusable references
- Allows extension developers to create flexible, context-aware field captions

## Quotes

- "It lets you create dynamic captions that change based on data or context" (Explains the core value of CaptionClass - enabling flexible, adaptive captions in extensions)
- "All Dimension fields use the CaptionClass property." (Provides a concrete example showing how CaptionClass is already used in standard Business Central for dimension handling)
- "There are 7 Codeunits in the Base Application that implement CaptionClass, including Dimension CaptionClass Mgmt." (Directs developers to reference implementations they can study and learn from when building their own solutions)
