By default, Cloud Dataprep can access data within the Google Cloud Platform project from which Cloud Dataprep is run. To give your Cloud Dataprep project access to a Google BigQuery dataset owned by a different Google Cloud Platform Console project, you must make the dataset accessible to the service accounts in your Cloud Dataprep project.
Finding your project's service accounts
Here are the Cloud Dataprep-related services accounts that you will find listed on the Google Cloud Platform Console IAM & Admin→Permissions page of your Cloud Dataprep project:
- Google Compute Engine:
- Cloud Dataprep:
Granting service account access to a BigQuery dataset
