Using a data page with a predefined key enhances performance by leveraging the caching mechanism of Pega. When a data page is loaded with a specific key, it is stored in memory. Subsequent accesses to the data page with the same key do not require fetching the data again from the external data source, significantly reducing the access time. This approach is particularly beneficial in cloud deployments where network latency can impact performance. It ensures that once the data for a particular customer is fetched and stored in the cache, accessing the same customer's information again is much faster, addressing the performance issue reported.References: Pega Community documentation on data pages and performance best practices.

A keyed data page is best used for data that does not change frequently and can be retrieved by a unique key. A long list of vehicle parts that rarely changes fits this criterion because the data can be cached and doesn't require frequent updates, optimizing performance.

At 4.5 hours after the case reaches the assignment, the SLA would have passed the goal and deadline, and entered the passed deadline period. The initial urgency is 15, the goal adds 10 (total 25), and the deadline adds 15 (total 40). After the passed deadline, the urgency increases by 10 every hour up to a limit of 10 events. By 4.5 hours, there would have been two passed deadline events, adding 20 to the urgency, leading to a total urgency of 60. References: Pega Platform Help - Service Level Agreements.

The recommended practice is to set the Access time-out value for the child case to be greater than the parent case time-out value. This ensures that the child case does not become inaccessible due to a time-out while the parent case is still active, which could happen if it had the same or a shorter time-out value. References: Pega official documentation on locking strategies and time-out values.

For each scenario, the appropriate mobile application solution is as follows:

"SDK application" is suitable for Globobank's scenario because they want to build a mobile app of its Pega Platform application to embed in its mobile app. The SDK would allow them to integrate Pega's capabilities within their existing mobile application environment.

"Signed application" is needed for Metrobank, which wants to distribute their mobile app on Android and iOS app stores. For an application to be accepted on these platforms, it must be properly signed with a developer certificate.

"Unsigned application" fits the scenario for Localbank, as they want to build a mobile app for a Pega Platform application but cannot distribute developer certificates to app developers. An unsigned application does not require these certificates, allowing development to proceed without them.

Based on these explanations, here are the matched solutions:

SDK application -> Globobank wants to build a mobile app of its Pega Platform application to embed in its mobile app.

Signed application -> Metrobank wants to build a mobile app for distribution on Android and iOS app stores.

Unsigned application -> Localbank wants to build a mobile app for a Pega Platform application, but developer certificates cannot be distributed to app developers.

The primary purpose of a production ruleset is to allow rules to be updated in a production environment. Production rulesets are designed to hold rules that business users can modify directly in a production environment without requiring a deployment from development through testing environments. This enables quick changes to be made to decision tables, correspondence, and other rule types that business users are permitted to change. References: Pega official documentation on ruleset types.

To create a custom status named Open-Review to be applied to assignments in one application, create a Field Value record named Open-Review for .pyStatusWork with the Apply To class set to the class group (A). This approach allows you to customize the status values used in your application and ensure that they are available for use in assignments within the specified class group, which typically corresponds to an application.References: Pega Community documentation on Field Value records and status values.

When integrating multiple Pega Web Mashups into a single page, it is necessary to identify unique names for each mashup to ensure that they are embedded and function independently without conflict on the client's page. References: Pega Platform Help - Pega Web Mashup.

To enable property-level encryption for sensitive data such as SSN and Account Number, you create an Access Control Policy of type PropertyEncrypt. This policy specifies which properties should be encrypted and how the encryption should be applied. References: Pega Platform Help - Access Control Policies.

When creating a pre-processing data transform, you should consider the timing of the commit for the flow action and the effect if the flow action is reloaded. These factors can impact how the data transform processes data and how it integrates with the flow action's lifecycle. References: Pega Platform Help - Data Transforms.
