What should be used to see a complete chronological list of a case's field edits, associated emails, case comments, and edits to related objects in a single view while working on a case?

• A. Create a custom-related list on the case.
• B. Create a custom report.
• C. Create a custom view on the Case tab (or Case Feed).
• D. Create a custom Visualforce page.

Answer: (A)

The thing being tested is how to view a complete, in-context timeline of everything that happened on a case in one place. A custom-related list on the Case page makes this possible by surfaceing all relevant related records directly on the case record. You can tailor this list to include the Case History (field edits), Email Messages, Case Comments, and edits to related objects, so as you work on the case you see a single, chronological view of all updates without switching contexts or jumping to separate reports.

This approach is practical because it brings the entire activity history into the Case view itself, keeping the support agent's focus on the case. A custom report wouldn’t sit on the Case page or update in real time as you work. A custom view on the Case tab or Case Feed isn’t dedicated to a single case’s complete history in one place, and a custom Visualforce page, while possible, requires more development work and maintenance.
