To support offline use of applications on mobile devices, you should source UI elements such as drop-down lists using data pages, which can be configured to be available offline. This allows the application to use locally cached data to populate the UI elements even when the device is not connected to a network. References: Pega Mobile Developer Guide on offline capabilities.

The function of class mapping for reports is to retrieve data from an associated database table. Class mapping determines which table data is pulled from when running a report, ensuring that the report includes the appropriate data based on the class structure. References: Pega official documentation on class mapping and reporting.

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.
