Final answer:
The process is known as filtering, which allows you to view a subset of a PivotTable report that meets certain conditions.
Step-by-step explanation:
The process of viewing a PivotTable report for a subset that meets a specific criterion only is known as filtering. Filtering allows you to narrow down the data in your PivotTable to only display the information that meets certain conditions, enabling a more focused analysis of the data. To filter a PivotTable in Excel or a similar spreadsheet program, you can use the filter drop-down menus on the PivotTable fields, where you can select or deselect items to display only the data that fits your criteria.
