What is required in the results tab of a custom KPI search?

In a custom KPI search, it is crucial to have only one field with a defined summary in the results tab. This requirement is in place because KPIs (Key Performance Indicators) are designed to measure specific business objectives with clarity and precision. Including only one field helps in focusing the analysis on that particular metric, allowing users to gauge performance effectively.

Moreover, having a defined summary for that field allows for proper aggregation, such as sums, averages, or counts, which is essential for interpreting KPI values meaningfully. If multiple fields were included without summary definitions, it could lead to confusion about what the KPI is truly measuring, diminishing the utility of the search results. Thus, the requirement of one field with a defined summary ensures that the custom KPI search yields actionable insights without ambiguity.
