### Create a dataset for query troubleshooting

To enable Ads Data Hub support team to troubleshoot your query, you'll need to
write the output of your query to a new troubleshooting dataset and grant the
support team BigQuery Data Viewer (`roles/bigquery.dataViewer`) access to the
dataset. This allows the team to view output of your query, without granting
access to any other data in your Google Cloud project. You can revoke access at
any time.

1. Designate a support dataset during [account
   setup](https://developers.google.com/ads-data-hub/guides/account-setup#bigquery_dataset). We
   recommend naming it `adh_support`. Ads Data Hub creates the dataset if it
   doesn't exist and grants your service account BigQuery Data Editor
   (`roles/bigquery.dataEditor`) access to it. You can view the designated
   dataset under **Account settings** . To change the support dataset after
   setup, [contact Ads Data Hub
   support](https://support.google.com/ads-data-hub/contact/adh_support).

   If you create the dataset in BigQuery yourself instead, grant your service
   account BigQuery Data Editor (`roles/bigquery.dataEditor`) access to it.

   If you are planning to use VPC Service Controls, your dataset must be within
   the service perimeter.
2. Grant [adh-support-team-noreply@google.com](mailto:adh-support-team-noreply@google.com)
   BigQuery Data Viewer (`roles/bigquery.dataViewer`) access to the support
   dataset. Optionally, give the dataset a [default expiration
   time](https://cloud.google.com/bigquery/docs/updating-datasets#table-expiration),
   so that results are automatically deleted.

## Unsupported areas

The Ads Data Hub Support Team doesn't support questions about:

- Using the Ads Data Hub API. Create issues on [Ads Data Hub's Google
  IssueTracker
  component](https://issuetracker.google.com/issues/new?component=650788). Issues with query *results* can still be sent to the [Ads Data Hub Support
  Team](https://support.google.com/ads-data-hub/contact/adh_support), whether the query was executed using the UI or the API.
- Writing queries from scratch
- Query optimization: fine-tuning queries to generate a specific dataset or for marginal performance improvements
- Discrepancy between in-product and Ads Data Hub measurement vendor reports. Reach out to your Ads Data Hub measurement vendor directly to troubleshoot such discrepancies.
- Trouble accessing the Ads Data Hub UI.
  - Ensure that you have been added as a user to an Ads Data Hub account.
  - Try using a supported browser. Only Chrome is officially supported.
- Feature requests
- Non-troubleshooting issues related to product changes. Work with your Google Account Manager to understand how product changes impact your use case.
