Refresh data Power BI Report Server vs file xls

Hi community,

I would know how to connect power bi report server at Excelfile source and define scheduled refresh.

In a past, I have used analysis service.

At the moment i have two questions:

1. Is correct to set the details mode in the same path ( ... / Manage / Data sources)  ?

2. Does the excel file have to be in a directory that is visible to the Power BI Report Server? If you have to do it at IT level (open the gateway) and the server where Power BI Report?

Thanks in advance for you support

Best regards,
Fabio
