Description

Indicates whether a value for the physical field in the underlying table is required.

Use Required to find out if a field in a dataset must have a value. If Required is true, the field must have a value. If Required is false, the field can be left blank.

When adding field definitions to a dataset, set Required to specify whether blank values for the new field should be prohibited.
