Connecting to existing datasets

[mauropasi]

Has anybody been able to connect to an existing dataset?

I have succeded in getting data to the Desktop application using an OleDb connector but then the service refuses to authenticate so I can't keep the report updated.

Any help is appreciated here.

Mauropasi,

Are you using the on premisis data gateway?  Since you say the service refuses to authenticate are you seeing the error when you are creating the connection in "Manage Gateways"?  I'd be sure I'm using the same credentials when defining the connection in Manage Gateways as I'd used when I connected to the data in the Power BI Desktop.  If all else failed I'd start by making sure whatever user I did chose to use in the connection had the highest priveledges possible on the database to start.  If I got things working then I'd like it back.  I'd also check the gateway logs.  There are two logs that it creates on the system where it is installed.  One is config type data but the other is actual query request type data so thats the one I'd look for.

Hi @mauropasi,

It seems you want to refresh OLEDB dataset published in the service, right?

As the OLEDB is a on-premise data source which requires gateway to build connection between the Power BI service and data source. You can install the personal gateway on the server which hosts the OLEDB data source, then configure the dataset to use this personal gateway. For more information, see: Power BI Gateway - Personal.
