Exam CAS-PA topic 1 question 23 discussion

Agreed, B is correct. This is almost verbatim from the docs page: RELATED LIST CONDITIONS: Include a relationship with another table in the conditions. For example, you could create an element filter on the Groups breakdown source, which uses the Group [sys_user_group] table. If you added a related list condition on Incident [incident]->Assignment group, you would get only groups that had an incident assigned to them. If this condition included [[Created][on][Last 6 Months]], you would get groups that were assigned an incident that was created within the last six months. https://docs.servicenow.com/bundle/xanadu-now-intelligence/page/use/performance-analytics/concept/c_BreakdownElementFilters.html

To get only groups that had an incident assigned to them on the Elements Filter record for the ‘Groups’ Breakdown Source, you use the condition: B. By adding ‘Incident->Assignment group’ to the Related List Conditions. This configuration ensures that the breakdown includes only those groups that have been associated with incident assignments, allowing for more targeted analysis and reporting within Performance Analytics.
