Which function allows you to add calculated fields to a report?

The ability to add calculated fields to a report is encompassed within the function of report customization. When customizing a report in NetSuite, you can create formulas and calculated fields based on the data included in the report. This means you can derive new values from existing fields, allowing for deeper analysis and tailored information presentation reflective of specific business needs.

Report customization provides the flexibility needed to add these calculated fields directly to the report’s layout, ensuring that they can be displayed alongside other data. Custom formulas can incorporate various mathematical and logical operations, enhancing the report's usefulness for decision-making.

Other options do not directly relate to the addition of calculated fields. Data customization typically focuses on configuring data elements and structures rather than specific report enhancements. Report filtering aids in narrowing down the data displayed but does not allow for the creation of new calculated fields. Report formatting, while important for the visual arrangement of the report, does not involve the calculation of new data elements.
