When would you primarily use a value group in Pega?

Using a value group in Pega is primarily intended for holding a set of unique values in an unordered manner. Value groups are collections that allow you to manage multiple unique values efficiently without the need for a specific order. This makes them particularly useful when you need to handle data that does not require sequencing, such as flags, feature toggles, or any other criteria where the order does not affect the application logic.

In contrast, the other options focus on different functionalities. For instance, aggregating multiple page lists pertains to handling structured data collections rather than unique value sets. Storing complex data types typically involves using data classes or other data structures, whereas managing user role assignments is more about application security and user access control, generally handled through role-based access configurations rather than through value groups. Therefore, the primary use of a value group aligns well with its definition of holding unique values.
