Which steps can a technical consultant take to allow multiple permits for a single application?

The correct choice involves adding an Aggregate Group to the Expression Set. This step is crucial when managing data that requires summarizing or organizing multiple permits associated with a single application. By using an Aggregate Group, the technical consultant can effectively categorize the permits, allowing for clearer data representation and manipulation within the system.

The use of an Aggregate Group allows for the combination of related entries, which is particularly useful in public sector scenarios where various permits may be related to a single application. This feature facilitates enhanced reporting capabilities and better visibility of the total number of permits linked to the application.

While other options, such as adding a lightning component or providing permission sets, may relate to broader aspects of application functionality, they do not specifically address the requirement for aggregating and managing multiple permits within a single application context. The Aggregate Step with the SUM function would be valuable for calculations, but it does not directly support the structural organization needed to manage multiple permits under one application consistently. Thus, the addition of an Aggregate Group is the most effective approach in this scenario.
