Just a quick post to highlight that the issue with setting the credentials for a Project Online OData connection that contained the [] for localisation is now fixed in the Power BI Service. If your OData URL contained the [] to specify the OData localisation you couldn’t set the credentials in the Power BI Service for the data refresh, you would see the error below.
For the details on the error see a previous post of mine, see the Note halfway down the post: https://pwmather.wordpress.com/2017/02/10/projectonline-ppm-powerbi-report-pack-publish-bi-reporting-powerquery-dax-office365/
It’s good to finally have this issue fixed in Power BI. The Project Online Power BI report pack I created will now refresh / work as expected in the Power BI Service: https://pwmather.wordpress.com/2017/01/03/projectonline-ppm-powerbi-report-pack-bi-reporting-powerquery-dax-office365/
