# Set persistent values

This action lets you [set persistent values](https://developers.google.com/analytics/devguides/collection/gtagjs/setting-values) to all accounts for the following page views and events. This is great for setting custom dimensions and metric values that should persist for every hit.

{% hint style="info" %}
**Note:** The data persistence model may not be intuitive, please be sure to learn more about setting [custom data fields](/analytics/adobe-launch/gtag/configuration.md#custom-data-fields) taking note of the "Data Persistence" section.
{% endhint %}

{% hint style="danger" %}
**Note:** There is a bug with the set command for GA4 in the native Gtag library (owned by Google). It is recommended that you add the event parameters for each event, rather than using the set persistent values action if you are using GA4.
{% endhint %}
