RANK within group when filtering

Hi,

 

I have the following data table in Power BI with a sequence by acct with highes value to lowest value:

 

AcctLocationKeyValueTypeSeq
1AAB300PH1
1AAC550HE2
1AAD700PH3
1AAE788HE4
1AAF980PH5
2BBA450HE1
2BBB480PH2
2BBC700PH3

 

If i place the data in a table in Power BI and filter by Type = "PH", i get this:

 

AcctLocationKeyValueTypeSeq
1AAB300PH1
1AAD700PH3
1AAF980PH5
2BBB480PH2
2BBC700PH3

 

What I want is a new measure that will re-rank the sequence based on the filter like this:

 

AcctLocationKeyValueTypeSeq
1AAB300PH1
1AAD700PH2
1AAF980PH3
2BBB480PH1
2BBC700PH2

 

thanks

Scott

Rank = 
IF (
    HASONEVALUE ( 'Table'[LocationKey] ),
    RANKX ( 
        CALCULATETABLE ( 
            VALUES ( 'Table'[LocationKey] ), 
            ALLEXCEPT ( 'Table', 'Table'[Acct], 'Table'[Type] ) 
        ),
        CALCULATE ( 
            SUM ( 'Table'[Value] ), 
            ALLEXCEPT ( 'Table', 'Table'[LocationKey] ) 
        ),,
        ASC,
        Dense
    )
)

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!

Please also try this measure expression, that should also work when there is no external filter on Type (i.e., match your original sequence #s).

Acct Rank =
RANKX (
    CALCULATETABLE (
        SUMMARIZE ( T5, T5[Type], T5[LocationKey] ),
        ALLSELECTED ( t5 ),
        VALUES ( T5[Acct] )
    ),
    CALCULATE ( SUM ( T5[Value] ) ),
    ,
    ASC
)
