To add data elements to create a custom ad hoc query, use which section?

• A. Subject Area
• B. Data Elements
• C. Query Builder
• D. Filter

Answer: (A)

Subject Area is the place you use to add data elements because it defines the domain of data you’re querying and groups the related fields you can pull into your ad hoc report. When you start a custom query, you first pick a subject area that matches the data you need (for example, a sales domain or a patient data domain). Within that area, you can browse the available data elements and add the specific fields you want to include in the query. The Data Elements list is essentially the catalog of fields, but you access and select them through the Subject Area so the query stays organized and scoped to the right dataset. The Query Builder is where you define how those elements relate and how calculations or joins work, while Filter is used to restrict results with criteria. So, to add data elements for a custom ad hoc query, you work through the Subject Area.
