To configure an XMLA endpoint in Power BI Report Builder, follow these steps:
1.Enable XMLA Endpoint: Ensure that the XMLA endpoint is enabled in your Power BI Premium capacity. You can do this by navigating to the Power BI Admin portal, selecting “Capacity settings,” and enabling the XMLA endpoint under the specific capacity settings.
2.Connect to the XMLA Endpoint: Open Power BI Report Builder and create a new data source. Choose “Microsoft Analysis Services” as the connection type and enter the XMLA endpoint URL. This URL typically looks like .powerbi://api.powerbi.com/v1.0/myorg/{workspaceName}
3.Set Credentials: Provide the necessary credentials to access the XMLA endpoint. This usually involves using your Power BI account credentials.
Once connected, you can create datasets by writing DAX queries or using the query designer to fetch data from your Power BI datasets.
Regarding the support for XMLA data sources in Power BI Service’s Deployment Pipelines, XMLA data sources are still supported. You can use XMLA endpoints to manage and deploy datasets within Deployment Pipelines.
