It's become clear to me that I cannot combine multiple tables to create a single report within the Power BI Service, that I must use BI Desktop instead, and then upload to BI Service. So, my question is how do I get that functionality, as well as importing other file type like MS Access, when my team and I are only using Office 365, without locally installed Office products?
I'm very big on Office 365 (I have an E3 subscription), but am now realizing that the Office products available through the service are much less capable than with locally installed software, particularly Power BI. How can I make up the difference without installing the full Office products locally?
