# Activate a session trait

When you are ready to make the session trait available for use in Sitecore CDP, you must activate it to change its status from *Draft* to *Active*. After a session trait is activated, it cannot be edited. If you need to make changes, you will have to pause an active session trait before editing.

Only team members with a *Developer* or *Admin* role in Sitecore Cloud Portal can activate a session trait.

To activate a session trait:

1. Open the session trait and in the top-right corner, click **Activate**.
2. In the confirmation dialog, click **Activate**. This action [changes the status](https://doc.sitecore.com/cdp/en/users/sitecore-cdp/developer-center/session-traits/session-trait-statuses.html "Session trait statuses") of the session trait to *Active* and makes it available for use across all [customer web sessions](https://doc.sitecore.com/cdp/en/users/sitecore-cdp/en/session-trait-limitations.html). Calculations are performed only after the session ends and the resulting values are stored in the customer's [guest profile](https://doc.sitecore.com/cdp/en/users/sitecore-cdp/developer-center/session-traits/defining,-storing,-and-accessing-session-traits.html#UUID-79889d12-06ee-5109-5ac2-083d17151698_section-idm234360187253341 "Storing a session trait against a guest") for future use, for example in creating segments and audience exports.

    Once the session trait is activated, you can track its successful and failed executions by reopening it and viewing the statistics on the **Activity** tab.
