I'm trying to use the on-premise gateway for a model that has an on-premise SQL server and Dynamics 365 (online) data sources.
I have successfully installed both the personal and on-premise gateway, but I cannot switch between the two; the option to switch to "use a data gateway" is greyed out.
I have added the SQL Server as a data source without issue. When I try to add Dynamics 365 (online) though I have to use a Web data source type as the OData data source type doesn't work - OAuth2 ins't an option, the credentials don't work if I use Basic and the URL isn't recognised if I use Windows. I'm not sure how important this is...
In theory this should work, I have built a bunch of models that mix on-prem and cloud data sources. Not sure of what you are seeing specifically though. Unless I am totally losing it, but I'm pretty certain that I have built CRM Online dashboards that mash-up on-premises data but I will have to go back and check. I do know that I was having some issues with refreshing my CRM Online dashboard due to OAuth2 issues, that's in another thread somewhere.
