Hi there :
So why I'm still not able to see it when I log in AGO in PowerBI and try to add a reference layer ? I always get the "No results found" message.
This topic covered a similar issue.
If you scroll to the bottom of the discussion, it indicates how to sign in using the ArcGIS account rather than the Power BI account.
Hope this helps.
Thanks for the clue but unfortunately, it doesn't work neither with my Entreprise nor ArcGIS login accounts.
However, it works if I create a feature service directly from AGO with data uploaded in AGO.
It looks like Feature Services published by ArcGIS Server and added to my ArcGIS Online account can't be used as Reference Layer in Power BI. Even if I set the security level to Public in both AGS and AGO, my feature service is not available a reference layer in Power BI.
Anybody from ESRI could confirm that ?
