OData feed cannot Edit Credentials in Service so cant refresh

[RoseyAlexa]

I created a report in Power BI Desktop and published it to the Service.

The OData Feed from Rapport 3 is fine in Desktop, but in the Service the data cannot be refeshed. It gives an error message saying that I need to Edit the Credentials, but the Edit Credentials is greyed out.

I have checked in Desktop that the Data Feed Crednetials are fine, and that the permissions are set to Organisational.

I have also checked that I can set up a Dataflow within Service, to the same ODataFeed. However, this would seem to suggest that it wants me to use the Dataflow instead of the original Dataset. Do I have to rebuild the report and Edit the Dataflow to make the same Query modifications all over again?

Why cant I Edit the Credentials within Service?

Dang it.

Might have found the answer myself.

The same Dataset has a small Excel file too. Once I removed that, it works OK. So it appears that its the Excel file, not the OData feed.

The Excel doesn't need refreshing. I can manually update that every 6 months or so.

So why is that stopping the OData from refreshing?

@RoseyAlexa,

In the same PBIX file, do you connect to Excel file stored in disk? Do you connect to on-premises OData service or online OData service?

If you connect to Excel file stored in disk and online OData service in same dataset, you are combining on-premises data source and online data source in a single dataset, in this case,  you would need to configure gateway to refresh the dataset. If the gateway is not configured properly, you would get the above error.

If you connect to  Excel file stored in disk and on-premises OData service in same dataset, you would also need to add excel data source within gateway to make refresh work.

It would be handy of there was a simple explanation of what CAN and CANT be linked together and how this affects refreshing and updating datasets.

All the Power BI info points you to "you can connect to ANYTHING, really simply", where it should say "certain data sources need additional setup".
