Which of the following is NOT a function of summary types?

Summary types in SuiteAnalytics are designed to provide aggregated data to facilitate analysis and reporting. Functions such as displaying maximum values, grouping data by specific criteria, and summing the values of a column are direct functionalities supported by summary types.

Displaying maximum values allows users to identify the highest entries within a dataset, thus enhancing the understanding of performance thresholds or top performers. Grouping data by specific criteria helps in organizing information to make comparisons or observe trends across different segments or categories. Summing values enables users to obtain total figures, providing insights into cumulative measures within the dataset.

The calculation of percentages, while useful, is not a direct function of summary types. Percentages usually result from taking summary results and deriving proportions based on totals, rather than being an inherent function of the summary types themselves. Therefore, this makes it the correct answer to the question, as it does not fit into the primary functionalities provided by summary types in SuiteAnalytics.
