Ranking and sorting

[GuinabaPBI]

Hello experts,

Using the below function, I am getting the table1

Rank:=if(not(isblank([bias])),rankx(ALLSELECTED(IBPData[Product Group]),[Bias],,0),blank())

table1

Table IBPData
Location	Product Group	Vol	Rank
A	Beer	1000	1
A	Wine	950	2
A	Water	820	3
B	Wine	980	1
B	Water	950	2
B	Beer	920	3
C	Beer	1100	1
C	Water	970	2
C	Wine	810	3

However, I'd like to get the table2 (below) just showing the top 2 products with the highest vol. across all the locations:

table2

Table IBPData
Location	Product Group	Vol	Rank
A	Beer	1100	1
A	Beer	1000	2
B	Wine	980	3
C	Water	970	4
D	Beer	960	5
A	Wine	950	6

Rank := // Try this one
IF (
    NOT ( ISBLANK ( [bias] ) ),
    VAR TopN := 2  // Specify the number of top products you want to include
    RETURN
        IF (
            RANKX (
                ALLSELECTED ( IBPData[Product Group] ),
                CALCULATE ( SUM ( IBPData[Vol] ) ),
                ,
                DESC,
                Dense
            ) <= TopN,
            RANKX (
                ALLSELECTED ( IBPData[Product Group] ),
                CALCULATE ( SUM ( IBPData[Vol] ) ),
                ,
                DESC,
                Dense
            ),
            BLANK ()
        )
)

Rank := //Try this 
IF (
    NOT ( ISBLANK ( [bias] ) ),
    RANKX (
        ALLSELECTED ( IBPData[Product Group] ),
        CALCULATE ( SUM ( IBPData[Vol] ) ),
        ,
        DESC,
        Dense
    ),
    BLANK ()
)
//And then filter out this measure less than or equal to 2 in visual filter
