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:
