In the workflow of extending a dimension via User Extensions, after creating a sandbox and editing the logical star, what is the next step to expose the customized elements?

• A. Publish the sandbox to production.
• B. Test the changes in a dev environment.
• C. Document the changes for governance.
• D. Modify an existing subject area to expose the required customized elements.

Answer: (D)

When you extend a dimension using User Extensions, the new elements are defined in your sandbox, but they aren’t available to reports or analytics until you expose them. The way analysts access data is through subject areas, which curate which data items are visible. So the next step is to include the customized elements in a subject area. By modifying an existing subject area (or creating one) to expose these new elements, you make them accessible in analyses and dashboards. After they’re exposed and tested, you’d progress to publishing the sandbox to production as part of the deployment process.
