Hi Support Team

We want to connect to tables in Azure Databricks via Power BI. We are able to connect this via Power BI Desktop but when we try to Publish the same, we can see the dataset associated does not refresh and throws error from Powerbi.com

It seems it is down to firewall settings configured at Azure Dababricks side which prevent any Public IPs to access the same. Our network support team has asked us to provide a dedicated IP address or range which will be used by Power BI cloud to connect against Azure Databricks so that they can whitelist the same.

Could you please suggest how we can provide dedicated IPs here or other potential solution here.

I did try to get VNet configured followed by creating a VNet gateway on the Power BI side and IP range for the subnet provided to Azure Databricks teams but it does not seem to solve the issue as we can see the dataset says either gateway or datasource not configured properly when try to map the same.

Could you please suggest the best solution on how we can solve this issue or if there is any particular configuration which you think could have made an impact here?

Hi Rohit,

What is the error message you get?

Also, on a side note, after you publish the report to PowerBI service, do you change the data source credentials to a service principal or a tech user? I am curious to know the best practice here i.e. develop reports in desktop using individual user ids, publish and change credentials to point to those of an Azure Databricks Service principal (or a tech user, that has got READ access on the delta tables/views). If there is a need to see which user is exploring the data, then provide "Direct Query/Live Connection" capability so the users are authenticated in Databricks (else, the service principal or tech user will run the SQLs to Databricks)

Hi Noor

Thank you soo much for your response. Please see the below details for the error message. I just got to know that Power BI are Azure Databricks are in different tenants.

Do you think it causes any issues? Do we need VNet peering to be configured here or something?
