Whenever a conversion value updates, the __CV update__ activity helps you identify which updates made it to the device.  By using the `{sk_conversion_value_status}` placeholder, this activity also reports the status of the conversation value update as `success`, `pending`, `TimerExpired`, or `CVWindowExpired`.

Using this activity and its supported placeholders can aid you in further analysis such as conversion value based reporting.

❌  - The event activity __is not__ included in your global callback. 

Depending upon your data export method, update your [CSV definition](/en/article/cloud-storage-uploads#format-your-csv-definition) or [callback URL](/en/article/callback-structure) with the supported placeholder in the table below.
