Thanks for the feedback, sorry for the late reply but I was on holiday.
Okay that might work for the "binary pbix to PBI service" scenario, but I see the following limitation for XMLA based data sets:
- Datasets created using the public XMLA endpoint aren't supported. To make changes to those data sources, the admin must use the Azure Analysis Services client library for Tabular Object Model.
So if I understand correctly, because we leverage some PPU workspaces where we deploy via XMLA (DEVOPS + Tabular Editor), we basically cannot go around the usage of Tabular Object Model, right? At least not for the initial deployment. I think XMLA deployments don't overwrite credentials, so that could potentially be, for now, an accepted caveat.
