Which privilege is necessary to access business rules and view the changes made to them?

To access business rules and view the changes made to them, the necessary privilege is associated with the ability to work with changesets, which is tied to the pyWorkOnChangeSet privilege. This privilege allows users to manage and interact with the change history of business rules, making it essential for viewing modifications, tracking updates, and understanding the current state of these rules within the application environment.

The other options pertain to different functionalities within the Pega platform. For instance, the pyManageVBD privilege relates to managing Versioned Business Data, which does not directly involve accessing business rules themselves. The pyRunSimulations privilege is associated with executing simulations to test scenarios or configurations, while pyTestFlows permits running flow tests for validating business processes. None of these effectively address the requirement of specifically accessing and viewing changes to business rules as pyWorkOnChangeSet does.
