Based on the available knowledge sources, Elementary’s Power BI integration provides end-to-end data lineage by connecting to Power BI using a service principal and accessing the Power BI API. The documentation specifies that you need to create and authorize a service principal, enable certain admin API settings, and connect Power BI to Elementary by providing tenant, client ID, and client secret. However, there is no explicit mention of support or limitations regarding the use of the on-premise data gateway between Power BI services and RDS in the context of lineage visualization. The documentation does note some limitations (such as not being able to analyze “My Workspace” and not currently supporting Paginated Reports, Dataflows, or Datamarts), but it does not address the on-premise data gateway scenario specifically. Therefore, I cannot confirm from the provided sources whether using the on-premise data gateway would impact the ability to use the Power BI connector for lineage visualization in Elementary. If this is a critical requirement, I recommend reaching out to Elementary support or your account representative for clarification based on your specific architecture and needs, as the knowledge sources do not contain enough information to answer this question definitively [Power BI Integration Guide](https://docs.elementary-data.com/cloud/integrations/bi/power-bi).
