How many levels of Breakdowns are available if Collect breakdown matrix is NOT checked on the Indicator?
D. 1 - Without the matrix, a single level of Breakdowns is collected. Explanation: In ServiceNow Performance Analytics (PA), the "Collect breakdown matrix" option determines how many levels of breakdowns can be collected for an Indicator: If unchecked (as shown in the image), only a single level of breakdown is collected. If checked, multiple breakdown levels (hierarchical breakdowns) can be collected, enabling more granular analysis.
B. There is no limit on the levels of Breakdowns collected.
The correct answer is D. 1 - Without the matrix, a single level of Breakdowns is collected. When the “Collect breakdown matrix” option is not checked, only a single level of Breakdowns is collected for the Indicator.By default, the interactive breakdown applies as the 1st-level breakdown. However, if the widget is on a breakdown dashboard and Follow element is selected on the Widget form, the interactive breakdown applies as the 2nd-level breakdown. (Collect breakdown matrix must be set on the indicator for 2nd-level breakdowns to apply.) Any breakdown that is set on a dashboard that contains the widget applies as the 1st-level breakdown.
