SAAS Tabular Power BI Desktop problem

I have a weird problem in Power BI Desktop. In SAAS Tabular Model I have created some measures which display there the correct result.

When I make a direct query connection from Power BI Desktop to the SQL Server Analysis services and display the measures, then BLANK() is displayed or a wrong value.
Can somebody please help me here? Thank you very much for a help in the correct direction!!!

Best Regards
Andy
