I am trying to connect via Fabric Datafactory dataflow gen 2, to a database stored in SSAS, but I have the following error from my windows authentication:
My gateway is online and my credentials there are ok with my windows credentials for SSAS, I haven´t problems with PBI Desktop and I even have reports on desktop using data sources from SSAS published in service with refresh working well.
any idea what could be happening, and how can i resolve this error?
thanks!!

Hi @RicLup ,
According to the error message, you need to set the map user in the data source for AS.
