Microsoft collaborated with Pyramid Analytics to develop the Power BI Desktop. Pyramid Analytics’ on-premise server-based technology complements Microsoft SQL Server Analysis Services, leveraging all the features of the Microsoft BI stack. You can now publish a Power BI Desktop file to Pyramid Analytics Server, and more features will be added over the next few months to enable seamless integration. We’re excited to collaborate in accelerating the delivery of innovative BI features that customers want and need most.
