the associated extract with new or changed fields.

The Data view appears, open on the
Datasets tab.
Click the dataset you want to refresh.

Data Visualization scans the table for changed fields. If no changes are detected,
no refresh is done and a notification is displayed. If changes are detected, the table
columns are updated and a notification is displayed about the change.
