Get latest value measure doesn't work in DirectQuery mode

[irisX]

Hello,

I'm trying to convert the power BI report data resource from Import to DirectQuery (Azure SQL). This measure is used to get the latest value for each category.

Measure =
VAR LatestTime = CALCULATE(MAX(Table[Time]), FILTER(Table, Table[Category] =1))
RETURN CALCULATE(AVERAGE(Table[Value]), FILTER(Table, [Category] = 1), FILTER(Table, [Time] = LatestTime))

It works fine in Import mode but returns nothing in DirectQuery mode. Also, it works if I use TODAY() instead of the calculated LatestTime in the RETURN line in DirectQuery mode, which means two filters work with the CALCULATE method, but an extra calculation fails?

There is no error or warning message displayed. I'm using Microsoft Power BI Desktop Version 2.82.5858.961 64-bit (June 2020).

Could someone please let me know which part causes the issue?

Thanks

Hi, @irisX 

You may try the following measure to see if it helps.

Measure =
VAR LatestTime =
    CALCULATE ( 
         MAX ( 'Table'[Time] ), 
         FILTER ( 
             ALLSELECTED('Table'), 
             'Table'[Category] = 1 
         ) 
    )
RETURN
    CALCULATE (
        AVERAGE ( 'Table'[Value] ),
        FILTER ( 
               ALLSELECTED('Table'),
               'Table'[Category] = 1&&
               'Table'[Time]=LatestTime
        )       
    )

About limitation and considerations in Direct Query mode, please refer to the document .
