For information on how to set up components for reactivity, refer to [Make Your Screen Elements Dynamic with Reactivity](https://help.salesforce.com/s/articleView?id=platform.flow_build_make_reactive.htm&release=264.0.0&type=5 "Use supported flow screen components, formulas, and screen actions to update screen components in real time without leaving the screen. With this reactivity, you can build screens that feel like single-page applications and reduce the number of screens that users have to navigate to complete tasks. This reactivity is supported with API version 59.0 and later.")

General Considerations

- Manual outputs of components don’t support reactivity. If you manually set a component output, that variable doesn’t change on the same screen when referenced in other components.
- Help text and labels don't react to changes in other components.
- Data types are required to match when you’re mapping an output to another component’s input to support reactivity.
- If validation rules exist for custom components, reactive changes don't trigger validation.
- The global variable $Flow is reactive. All other global variables such as Custom Labels, Custom Settings, $Organization, $Profile, are not reactive.
- When mapping a `DateTime` field to `Time`, the value is converted to GMT and stays converted when navigating between screens. If mapped to a `DateTime` field, the locale is preserved. For example, if the time value is 8:00 AM in your locale, the converted GMT time could be several hours off your time locale (such as 4:00 PM). Refer to A Note About Date/Time and Time Zones for information about Converting Between Date/Time and Text and Date/Time in time zones: [Using Date, Date/Time, and Time Values in Formulas](https://help.salesforce.com/s/articleView?id=platform.formula_using_date_datetime.htm&type=5&language=en_US)
