Data Source Authentication error in Power BI Server
The account I use for Data Source authentication shows following error when checking "Log in using these credentials, but then try to impersonate the user viewing the report " option but works fine...
I believe you need to add the account as admin on the SSAS server to be able to set EffectiveUserrName (i.em impersonate for SSAS).
May you please tell how to do it ?
