Top/Bottom Measure giving wrong value

[SW_Srinivas]

Hi Everyone,

I have a measure to calculate Top/Bottom/All as follows :

Top/Bottom  =

VAR NValue =

    SELECTEDVALUE ( 'Drop Down '[Values] )

VAR Ranking_TOP_CUST =

    RANKX (

        ALLSELECTED ( 'Sales'[Product Group] ),

        [Current Period Revenue],

        ,

        DESC

    )

VAR Ranking_Bottom_CUST =

    RANKX (

        ALLSELECTED ( 'Sales'[Product Group] ),

        [Current Period Revenue],

        ,

        ASC

    )

VAR Result =

    SWITCH (

        SELECTEDVALUE ( 'Top/Bottom'[Selection] ),

        "Top", INT ( Ranking_TOP_CUST <= NValue ),

        "Bottom", INT ( Ranking_Bottom_CUST <= NValue ),

        "All", 1

    )

RETURN

    Result

Top/Bottom[Selection] column has values : Top,Bottom,All

Drop Down[Values] column has values : 2 to 30

I have then pulled this measure into my table as a visual level filter and set it as : Show Item when Value is 1

Now, I have a Year slicer and a Previous Period Revenue measure. When I apply the Top/Bottom Measure ,and select a Year the Previous Period Revenue is showing minor difference than it should . 

Previous Period Revenue =

VAR YTD_ = CALCULATE([Sales Out DMS],INIT_RAW_SG_VN_CDS[FIS_YR]=max(INIT_RAW_SG_VN_CDS[FIS_YR])-1,ALL(INIT_RAW_SG_VN_CDS[FIS_YR],INIT_RAW_SG_VN_CDS[FIS_QTR],INIT_RAW_SG_VN_CDS[FIS_MTH],INIT_RAW_SG_VN_CDS[FIS_WK]))+0

I am not able to identify what is wrong.. Would appreciate help.. 

Thanks in advance...

Hi @Greg_Deckler 

My requirement is as follows:

i have a table visual which has Account Name, current period revenue and previous period revenue as values. 
I need to give 2 slicers .

1) to select Top/Bottom/All

2) to select number between 2 and 30

Now based on the slicer selections, my table visual should show change.

eg: if I choose All then it should show all Account Name.

if Top and 5 is selected, then table should show top 5 accounts with highest current period revenue. And similar for Bottom as well.
