What is an option when customizing a report?

Adding a filter is a fundamental option when customizing a report. Filters allow users to refine the data that is displayed, helping to focus on specific subsets of information that meet certain criteria. This capability enables users to tailor reports to their particular needs, such as viewing only transactions from a certain timeframe or highlighting accounts that fall within a certain balance range. By using filters effectively, the report becomes more relevant and easier to analyze for specific insights.

While summarizing fields can also enhance a report by consolidating data into summary metrics, it doesn't fundamentally change what data is included in the report itself. Scheduling a refresh time pertains more to report management than customization, and adding a gauge component is more about visual representation rather than altering the core data included in the report. Therefore, adding a filter is key to customizing reports effectively to meet user needs.
