Top/Bottom filter not working properly

[Chrisjr]

Hello All, 

I have the following visual :

When I selecet the top 3, the Ranking var mesrure in the last column gives me the result of the top 3. same for the bottom 3.

The problem is when I select a district in the filter "N distric"(each Dealer/Group Name belong to a District number)  , it gives me the top 3 but no values for  the bottom 3 . See below:

My data model :

The dax for the Ranking var is : 

Ranking var =

VAR _TopDealer = RANKX(ALL(Dim_dealers[Dealer/Group Name]), [Measure], , DESC)

VAR _BottomDealer = RANKX(ALL(Dim_dealers[Dealer/Group Name]), [Measure], , ASC)

VAR _ranking = IF(SELECTEDVALUE(TopBottom[Value] )= "Top", _TopDealer, _BottomDealer)

RETURN

IF(_ranking <= 'Ranking Option'[Ranking Option Value], [Measure])

The Ranking Option filter at the top is a paramter : 

        Ranking Option Value = SELECTEDVALUE('Ranking Option'[Ranking Option])

The Value filter is a table which I buid as : 

     TopBottom = {"Top", "Bottom"}

So, what could be wrong in my dax for not retuning values for bottom selection?

Thanks

Hi @lbendlin , 

Thanks for your answer. 

Please see the link below of the app and the dummy dataset :

https://drive.google.com/drive/folders/15gTkdnqpMhB_Ih3E1d4ECIHVDm5OSjL6?usp=drive_link

So, on the visual, when I select a top or bottom, it works well. 

However, the issue comes when I filter a LMA. for example below, hen I filter the LMA 10, then it does give me the top 3 but not the bottom 3. THe bottom selection is empty.

I cannot figure out it will not show me the bottom when I select a filter that has a higher hierarchy than deler. 

( A LMA owns several Dealers).

Thanks
