What must you do to add grand totals to the detail view of search results?

To add grand totals to the detail view of search results in NetSuite, you must check the show totals box on the results subtab. This feature enables the display of summarized numeric values, such as sums or counts, directly alongside the detailed data. By enabling the show totals option, users can quickly see overarching totals without needing additional calculations or summary reports, enhancing the usability and clarity of the search results.

The other options do not directly achieve the goal of displaying grand totals in the detail view. Manually calculating totals and entering them is not efficient and does not integrate with the dynamic nature of search results. Disabling all filters would alter the dataset being analyzed, likely complicating rather than simplifying the view. Using the summary type 'sum' is a technique for summarizing data but may not specifically affect the display in the details view, as it pertains more to a different context within the suite analytics. Thus, the correct approach is to utilize the show totals function for an immediate and integrated total view.
