I haven't made any changes to the data source settings, neither to the dataset. I have 3 different datasources in my dataset: Teradata, Oracle & SharePoint. This issue is with Teradata source. However, in PowerBi desktop the entire dataset is getting refreshed fine without any issues. Only in PowerBI service, I'm facing this error. Please help.

Hi @Puneeth_Acharya ,


From internal trace, I find the "User is not authorized" error. I would suggest you check if the data source in Manage Gateways and credential in Dataset Settings for the dataset are fine. Also please check the Privacy level setting for Teradata and Oracle data source in Manage Gateways section.
