You are right!
It's just to confirm the credentials and not is necessary to configure a gatway when just SharePoint is being used.
Thanks for this!
However, my application reads data from SharePoint and(+) SQL Server base. In this case, I have an on-premises gateway to refresh the SQL data and it's not working. Apparently, the PBI services is waiting a personal gatway, but I need an on-premises gateway. See the PBI message below.
I have used on-premises gateway for SQL data for other applications and it's work very well when just SQL data were used. SharePoint source can causes some problem or conflict?
Thanks!
