Hi @Sha abs ,
First, please confirm your SSAS database contain the data, connect to SSAS via SSMS, then run a query as below to see if it can return any data:
EVALUATE ROW ( "Total YTD", 'Usage'[TotalYTD]
If it does not return any data, you may need to confirm the processing to see if you have set to the correct SSAS server.
If it does return data, then you may need to check your Power BI report to see if there are any issues with your Power BI report.
