Merge or append on-premises and cloud data sources
The On-premises data gateway enables you to merge or append on-premises and cloud data sources in the same query. This is helpful when you want to mashup data from multiple sources without having to use separate queries.
- A gateway installed on a local computer.
- A Power BI Desktop file with queries that combine on-premises and cloud data sources.
In the upper-right corner of the Power BI service, select the gear icon > Manage gateways.
Select the gateway you want to configure.
Under Gateway Cluster Settings, select Allow user's cloud data sources to refresh through this gateway cluster > Apply.
Under this gateway cluster, add any on-premises data sources used in your queries. You don't need to add the cloud data sources here.
Upload to the Power BI service your Power BI Desktop file with the queries that combine on-premises and cloud data sources.
On the Dataset settings page for the new dataset:
For the on-premises source, select the gateway associated with this data source.
Under Data source credentials, edit the cloud data source credentials as necessary.
With the cloud credentials set, you can now refresh the dataset using the Refresh now option, or schedule it to refresh periodically.
To learn more about data refresh for gateways, see Using the data source for scheduled refresh.
