Troubleshooting issues or errors in the linking process
Linking accounts to Ads Data Hub where self-service linking is not available
Clarifying general schema questions
Troubleshooting query execution errors. To resolve common error messages,
review the Errors troubleshooter.
Troubleshooting data discrepancy issues with first-party reports — for
example, when Ads Data Hub results don't match Google Ads UI reports.
Troubleshooting unexpected query results
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.
Create a dataset in your BigQuery project named adh_support. If you are
planning to use VPC Service Controls your dataset must be within the service
perimeter.
Grant your service account BigQuery Data Editor
(roles/bigquery.dataEditor) access to adh_support.
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. Currently, 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.
