Summary of Extended analysis
Extended analysis in ServiceNow provides a deeper, more detailed level of data examination within explorations, enabling customers to uncover new insights and make more informed decisions. It aggregates records related to a response and analyzes Choice, Reference, and Boolean columns to deliver richer, unique insights beyond standard analysis.

Key Features
- Field Selection: Extended analysis examines visible columns in the record list and related tables, prioritizing Choice fields with the highest cardinality, followed by Reference and Boolean fields, based on the system property
snquerygen.hiddeninsights.groupby.minfields(default is 5). - Dynamic Field Search: If the visible columns are fewer than the property value, the system searches the table to include additional relevant fields until the threshold is met or no more eligible fields are found.
- Unique and Focused Insights: The system avoids repeating identical insights by drilling deeper into data subsets, which reduces the need for multiple follow-up questions and accelerates result delivery.
- Resource Considerations: Extended analysis consumes more system resources and processing time than standard analysis, so customers should apply it judiciously based on their needs.
- Activation Requirements: Requires the Query Generation analytics hidden insight skill to be active. Users can enable extended analysis within explorations or when launching AI Data Explorer.
Practical Use and Benefits
Extended analysis enhances exploratory data analysis by providing detailed metrics such as percentage changes, trend slopes, and variability measures (e.g., standard deviation and range). For example, when analyzing incident trends, it can reveal:
- Significant volume shifts between periods (e.g., a 49.2% drop in incidents month-over-month).
- Largest monthly increases and consistent trends (upward or downward) over time.
- Operational stability insights through variability metrics.
This deeper level of insight helps customers identify underlying patterns and operational shifts more effectively, aiding in proactive decision-making and resource planning.
Generate a deeper level of analysis that can reveal new insights, enabling you to make more informed decisions.
Extended analysis involves aggregating the records related to a response in an exploration. It examines the same columns that you see when you view the list of records for the relevant table. It takes a Count of Choice, Reference, and Boolean columns. Therefore, you can influence extended analysis by selecting which fields to view in the relevant tables. The relevant tables include any related tables that Query Generation dot-walks to.
The number of columns that extended analysis examines is set in the system property sn_query_gen.hidden_insights.groupby.min_fields. The default value is 5. If the number of eligible columns that are visible on the record list is lower than this value, the system searches for more fields on the table. The search stops when the total number of fields from both the list view and the table search reaches the value of the system property. If the system can’t find that many fields, it uses the fields it does find.
While the results of extended analysis usually enrich the responses in an exploration, the analysis takes more time and uses more system resources than a standard analysis. You have to use your judgment on when to employ it.
