An aggregate of latest value

[wesen]

Currently, am working on the report server and am collecting data on cumulative bases which mean every district report it cumulative performances. My database has three different tables one for the performance, one for the date and the other Is for the district. So that my power bi takes the sum of the aggregate of all district under a region. But I need an aggregate of last value from each district summed up, instead of all the value under a district. How can I do that?

Hi @wesen 

The below will fix the total.

Value 2 = 
SUMX(
    GROUPBY( 
        'Table 1', 
        'Table 1'[District Name],
        'Table 1'[country Name] ), 
    CALCULATE( 
        SUM( 'Table 1'[Value] ),
        LASTDATE( 'Table 2'[Entry_Date] ) )
)

@Mariusz It works for imported mode and thanks to you. But am using direct query mode(In power bi server) in which I'm unable to get DAX for GROUP BY AND LAST DATE. Can you suggest me any other solution?

Thanks a lot,

Hi @wesen 

Unfortunately, I'm not familiar with PIRS, I tried to find DAX functions supported and there is not much around.

The below is using SUMMARIZE instead of GROUPBY and MAX Instead LASTDATE, check if thats any better.

Value 3 = 
VAR _tbl = 
    ADDCOLUMNS(
        SUMMARIZE( 
            'Table 1', 
            'Table 1'[District Name],
            'Table 1'[country Name] ),
        "Max Date", CALCULATE( MAX( 'Table 2'[Entry_Date] ) ) 
    )
RETURN 
    CALCULATE( 
        SUM( 'Table 1'[Value] ),
        TREATAS( 
            _tbl, 
            'Table 1'[District Name], 
            'Table 1'[country Name], 
            'Table 2'[Entry_Date]
        )
    )
