You can add an alert to any data module in order to be notified if the data at the source source has changed.
If the module's 'Update' is set to 'manual', you will be asked to change the setting to 'Auto', so that the module does check for new data at the source. Learn more about data version control.
Once the alert is set, look out for the alert counter. For every new version that is found, you will receive an email alert.
Open the VERSION SELECT window to see a list of all the new versions, and load any one of them.
