Cracking the GA4 Code: A Simple Guide to Settings

Show or hide modeled data in reports

To see modeled data in your reports, choose the Blended reporting identity. You must be an Administrator to control this setting:

1. In Google Analytics, click Admin.
2. Make sure you are in the correct account and property.

3. In the Property column, click Reporting Identity.
4. Select Blended.
5. Click Save.

To stop seeing modeled data, select another option. The option you choose does not affect data collection or processing. You can switch between the options at any time without making any permanent impact on data. Learn more about Reporting identity.
