Error when updating composite model credentials to another Power BI Dataset

Hi All,

Starting today we are experiencing issues when updating the credentials for a Power BI dataset in a composite model. When we try to re-enter the credentials we get the following error:

Failed to update data source credentials: AnalysisServices: Failed to resolve the core XMLA server

This only seems to happen when we publish a new dataset or try to re-enter the credentials on a published (composite) dataset which connects to an existing Power BI dataset (through the API endpoint). See below screenshot:


Furthermore I'm experiencing this issue on multiple Power BI tenants in the Western Europe region, there seems to be a change in the Service which I can't get my hands to.

Can anyone confirm this is a bug in the Power BI service so that we can get a fix from Microsoft?

Thanks in advance!

Kind regards,

Ron Verhoeven

Hello Everyone,


Just to give an update on this. I got a response from Microsoft.


"This issue is a current known issue being worked upon by the Microsoft Power BI team actively. Our team shall soon announce the ETA for bug fix deployment, as a workaround it is recommended by the Microsoft Product group team to move your workspace to Premium Per User/ Premium capacity temporarily to configure the data source credentials"

That workaroud about moving the workspace to Premium and then back, but to no avail.
