Hi dseelam1 ,

Thanks for posting your query in the Microsoft Fabric Community. The error

ADBC: Could not create dataset _bqadbc_temp_tables

comes up because Power BI’s BigQuery connector tries to create temporary datasets and tables in the background when it runs queries. If your service account only has read only permissions, it won’t be able to create those objects, and that’s why you’re hitting this issue.

To fix it

  1. In the project linked to your BigQuery connection, grant the service account at least the BigQuery Data Editor role. That will let it create the temporary datasets and tables it needs.

  2. Alternatively, you can create your own dataset and grant the service account full access to it, then use that for staging.

  3. After updating the permissions, reconnect from Power BI Desktop and try applying the changes again.

With the right permissions in place, Power BI should be able to create the  _bqadbc_temp_tables dataset automatically and you’ll be able to publish without errors.

Regards,
CST_Team.

Hi V-yubandi-msft , Thanks for the reply.

 

Service account already has required edit permissions for the same dataset  where my source table reside. 
If its enough, how do I make it use the same dataset for staging?
I dont see any options within configs to provide this specific staging details.
