* A. Data reference:
* This field type is used to reference data from an external source dynamically. It allows the application to pull in data as needed without storing it directly within the case.
* D. Case reference:
* This field type is used to reference another case within the Pega application. It is useful for linking related cases and managing dependencies between them.
