Read-only fields
Fields in validation may be read-only. You can set the read-only option for a field on a validation form from the field properties in the Validation Form Layout window. For a table field, you can set the read-only option from the columns option of the table properties. For fields that are set to read-only for all validation steps, the best practice is to select the field properties ( or the table field properties ) Always valid option.
Content of a read-only field is grayed and an icon is shown left of the field that indicates that the field is not writable.
