Hi - sure - you need to go to Metrics & Data and then Data sources
Click on your data source. There, you’ll see a section called “assignment queries”
you can edit those to match your data

Copy code
SELECT
2 user_id as user_id,
3 timestamp as timestamp,
4 experiment_id as experiment_id,
5 variation_id as variation_id
6FROM
7 DBT_DEV.DBT_GROWTHBOOK.viewed_experimentthis table topically about registered users in my end

mixpanel should work
do you have multiple randomization units? (on that same page)
