To extend a table in ServiceNow, what must be true about the table?

• A. The extensible option is selected
• B. The table is global
• C. The table is read-only
• D. The table is a core table

Answer: (A)

Extending a table hinges on the base table being marked extensible. If the Extensible option is selected on the table’s definition, you can create new tables that extend it, and those child tables will inherit fields from the base. The other properties—whether the table is global, read-only, or a core table—do not determine whether extension is possible. A practical example is extending the Task table to create ITSM tables like Incident or Change; those extensions rely on Task being marked extensible, not on its global/core/read-only status.
