Related in Direct Query Mode

[RT6]

Hello! 

I am trying to do basic calculation Related in the Direct Query mode:

Sales Amount = RELATED('product'[Unit_Price]) * sales_streaming[Units]

and i get the following error:

Is there any work around to perform the calculation between two tables in the direct query mode?

Thanks!

Hi @RT6 

Did you use conditional formatting for your fields when your connection mode is Import ?

Hi @RT6 

This error is thrown when some aggregation (in this case the count) is been translated to M for execution, so it's not really SQL yet . You can check your query in Power Query Editor to see whether some queries affect your operation .

Hi Alisa!

Thanks fro your answer.

The issue is after any transformation in Power Query, like split columns, change data type etc i get the following error:

I need to maintain Direct Query connection. I can aggregate two tables for example, but i cannot change data type even in PB Desktop, so i cannot perform any calculations.

Any ideas? Thanks!
