A keyed data page is best used when a user selects a replacement part from a long list that seldom changes (B). Keyed data pages are designed to efficiently manage large amounts of data that do not change frequently by loading data specific to a key (like a part ID). This improves performance by caching the data and reducing the need to frequently query the source system for the same data.References: Pega Community documentation on data pages and caching strategies

To create a class join in a report definition, you must select the type of match for key values (A) and create a prefix for the joined class (C). Selecting the type of match, such as Inner Join or Left Outer Join, determines how records from the primary class and the joined class are combined based on matching key values. Creating a prefix for the joined class helps in distinguishing properties from the joined class from those of the primary class, preventing naming conflicts and clarifying the report definition. These actions are fundamental steps in setting up class joins in report definitions to retrieve and display data from multiple related classes.References: Pega Community documentation on report definition and class joins.
