B C To enable local warehouse managers to dynamically update the list of courier services based on performance and delivery metrics directly in the production environment, specific functionalities need to be leveraged within Pega. B . Delegate the records for the courier service data type: Delegation is a powerful feature in Pega that allows certain data types or rules to be managed by business users directly in production. By delegating the courier service data type, local warehouse managers can add or remove courier services as needed without requiring changes to the application code or direct database access. C . Define an approval process for adding and removing courier services: Implementing an approval process ensures that changes to courier services undergo review before becoming effective. This step maintains data integrity and service quality by ensuring only justified updates are made to the list of courier services. Creating an access group for local warehouse managers (A) is a necessary step for defining user permissions but on its own does not specifically enable the updating of courier service records. Enabling rule checkout (D) is more related to the development environment and rule versioning, not directly applicable to the business user's management of data records in production. Reference: Pega’s official documentation on data delegation and workflow configuration provides insights into enabling business users to manage specific types of data directly and securely, including the setup of approval processes for such changes.
