Can't refresh in PBI Service with ProjectOnline Datasource

[DataVitalizer]

Hi Community,

I have created a report on PowerBi Desktop with a Project Online Datasource, the refresh works perfectly on the desktop version but I am experiencing an error with the online refresh:

I thought maybe I had to enter the crendentials once again but I don't find the OAuth2 option

Thank you in advance.

Hi @DataVitalizer , 

Please try to modify your OData URL follow the step mentioned in this document: 

"If the address for your Project Web App site resembles https://<tenantname>.sharepoint.com/sites/pwa, then the address you’ll enter for your OData Feed is https://<tenantname>.sharepoint.com/sites/pwa/_api/Projectdata."

The OAuth2 authentication option should be available. 

Best Regards,

Hi @v-qiuyu-msft,

Yes, exactly that's what I have done but still can't get the OAuth2 method

Thank you in advance.
