How is the link between Group and Detail views established in searches?

The connection between Group and Detail views in searches is established by the field used for grouping. This field acts as a key to access more granular details about the grouped records. When a user selects a specific group in the Group view, the detail view displays all the related entries corresponding to that specific group. This design allows users to efficiently navigate from high-level summaries to detailed records, enhancing the overall usability of the search functionality in NetSuite.

In contrast, the other options do not accurately describe the relationship between these views. For instance, a detail view does not merely show unique records, as it presents all related entries for the selected group. Displaying all core fields in both views without distinction does not reflect how grouping is meant to streamline data presentation; rather, it helps differentiate between summary and detailed information for clarity. Lastly, while the detail view may focus on records related to the grouping criteria, excluding this criteria entirely would defeat the purpose of the grouping and would not aid in establishing the link between the two views.
