A data reference is a field in your data model that is linked to a data type in your application. When you add a data reference to a form, it prompts users to select a data record, or instance of the data type. By using data references, you can reuse information in your application and build forms that are easy to maintain.
Unlike fields and forms that are specific to a case type, data types are accessible throughout your application. You can create data references in different case types that are linked to the same data type.
The following techniques for referencing a data type are supported:
Adding a new field to a form and setting the field type to Data reference
Selecting a data type in the Reuse fields panel
This technique automatically creates and configures a data-reference field.
Selecting an existing data reference in the Reuse fields panel
Adding a data reference field to a data type or case type
