A quick Q&A-related tip. If you create a report in Power BI Desktop and use a Power BI service live connection:
…and then you put a Q&A button on the report, clicking on the button gives the following error message:
Q&A isn’t supported for reports that use DirectQuery data sources, live connections to older Analysis Services data sources, or non-English language models
However, this message only means that Q&A buttons do not work in Power BI Desktop with Power BI service live connections. If you publish the report to the Power BI Service you will find that the Q&A button does work correctly.
[Thanks to Seth Bauer and Aaron Meyers for the information]
Hopefully they can improve the error message in a future release!
