A few of our customers reached out to us for a Dynamics Navision connection from Power BI Desktop, and we successfully implemented a secure connection to NAV, following the process below, which I thought would be good to share with other users as well, who have a requirement to connect to the NAV server.
Specific users were not able to open the paginated report in the PBI service which used to work fine in PBI Report Server.
Could not connect to the data source. There was an error communicating with Analysis Services. Please verify that the data source is available, and your credentials are correct. The connection either timed out or was lost.
