In which class should a report definition rule be created?

The correct choice is to create a report definition rule in the same class containing the records to be reported on. This approach ensures that the report is specifically tailored to the structure and data contained within that class, allowing for efficient data retrieval and accurate reporting.

When a report definition is created in the same class, it can directly reference the properties and records without needing to navigate or filter through other classes. This linkage facilitates a clearer understanding of the data context, leading to more relevant report outputs. Additionally, it simplifies maintenance and updates to the report, as any changes in the data structure or requirements will be directly reflected within the report defined for that class.

Creating a report in a global class or a separate utility class may lead to unnecessary complexity, as these classes might not have direct access to the specific records or properties needed for the report. Choosing a parent class could result in a broader dataset than intended, which may overwhelm the report with irrelevant data from subclasses, losing the specificity and focus that the report should provide. Hence, aligning the report definition directly with its associated records in the same class ensures operational efficiency and relevance.
