What is meant by subtotalling the report?

Subtotalling a report refers specifically to the method by which intermediate totals are generated within the data set, allowing for a deeper analysis of groups or categories before arriving at the overall total. This action helps to break down the data into manageable sections, showing cumulative values for specific segments. By opting to subtotal, the report user can choose how they want to organize and summarize their data, enhancing clarity and enabling better insights into particular areas of interest.

The other choices address aspects of report preparation but do not specifically capture the essence of subtotalling. For instance, defining overall report objectives is about understanding the purpose of the report, determining the reporting format involves decisions about how data is visually represented, and simplifying report generation focuses on making the creation process easier. None of these options directly pertain to the specific action of calculating and displaying subtotals within the report data itself.
