Hi,
I got my Power BI gateway setup and got a live connection to SSAS tabular model. I can see the gateway is running and data is getting refreshed hourly.
I created my first report in PBI desktop and published it on PBI service. I am getting an error accessing the dataset.
1)First screenshot shows the error when I try to connect to SSAS through 'Get Data' feature.
It gives error "PowerBIErrorCode: DMTS_MonikerNotFoundError".
2)The second screenshot is when I go to my workspace and try to access my dataset/report.
It gives error "There was a data source access error. Please contact the gateway administrator"
I checked my UPN name. It matched with my username and it should not be an issue. Other thing is I am on Power BI Pro Trial version which was one of the answers suggested by user community, but I am not sure if it is the issue. Reason being, when I user an excel sheet data, and create a report in power bi desktop and publish it, it does not give any error.
Can someone please help me out ?
