Extend the scope of your report by displaying data from various classes. For example, if your report about insurance policies applies to the Work- class, you can include specific data from different classes by joining the classes together.
By default, report definitions include data from only the class to which the report applies. By using the class join functionality, you can make your reports more comprehensive.
In comparison with association rules, joins are not reusable across multiple report definitions, and apply only to the report that you edit.
