When a report is created in a class group (MyCo-HR-SelfService-Work), it will return instances of its child classes (MyCo-HR-SelfService-Work-TimeOff and MyCo-HR-SelfService-Work-Expense) unless those child classes are stored in different database tables due to class table inheritance or other data storage configurations.

Creating a new ruleset version for each team ensures that each team's work is isolated within a specific version, preventing overlap and conflict. Setting up a branch ruleset for each team further isolates development work, allowing parallel development streams that can later be merged back into the main application ruleset. These two options, when used together, provide the most flexibility for teams working on separate enhancements with uncertain release dates. References: Pega Platform Help - Branch Rulesets.

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.
