Tables must have the extensible option selected in order to be extended.

Tables must have the extensible option selected in order to be extended.

• A. True
• B. False
• C. Sometimes
• D. Only for some tables

Answer: (A)

Extending a table in ServiceNow relies on a simple rule: a table must be marked as extensible to have a child table that extends it. The Extensible checkbox on the table definition enables the inheritance relationship, allowing a new table to inherit fields from the base table and add its own. If that option isn’t enabled, the table cannot be extended, even if you want to create a specialized version of it. For example, you’d enable extensibility on a base table you intend to expand, then create a child table that extends it and adds additional fields. Therefore, the statement is true: tables must have the extensible option selected in order to be extended.
