Help with RANKX - Returning 1 for All Values

I am having trouble with RANKX- I am getting a 1 for each ranking.  I am trying to rank donations by Household ID.

 

I have a measure to sum up the donations for the period:

Donation for Pd = calculate( SUM(Donation_Distributions[Amount]),
ALLSELECTED ('Dates'[Date] )
)
 
I then try to use this measure to rank by Household ID using this formula:
Household Rank = RANKX (ALLSELECTED(Donation_Distributions[Household ID]), [Donation for Pd] )
 
I am getting 1 for each rank in my visual.  Is there something I am missing in one of my formulas that is causing this?
 
Thank you!

    Sure. So to break down what's happening, we need to understand how RANKX works.  

     

    You're skipping the <value> parameter, so the value of the expression at the current row is used instead.  So for every [Household ID], it's evaluating your [Donation for Pd] measure.

     

    It may be helpful to put all your [Household ID]s in a table visual with your [Donation for Pd] measure to make sure that every household isn't calculating the same amount for [Donation for Pd], which could cause all their ranks to be the same.  In which case, you need to fix your measure.

     

    The next option is to explicitly add [Donation for Pd] as the <value> parameter for your RANKX, so that RANKX knows what value should be ranked against all the other measure results.

      Ok, so I set this up in a visual.  When I add the fields Donation for Pd and Household ID it works perfectly.  I have another table that contains Household Name in a separate linked table.

       

      When I add in the Household Name field in the visual, this is what breaks my ranking and shows all as #1.  Do I need to somehow include this Household Name field in my formula?

        Instead of using ALLSELECTED(Donation_Distributions[Household ID]), just use ALLSELECTED(Donation_Distributions).  This returns all the columns of the Donation_Distributions table, instead of just the column of ID numbers.

         

        Try:

        Household Rank2 = RANKX (ALLSELECTED(Donation_Distributions), [Donation for Pd] )

    Hi Anonymous 

    It's only a gues, becose dont realy know the scenerio, but try removing ALLSELECTED ('Dates'[Date] ) from Donation for Pd.

     

    Donation for Pd = SUM(Donation_Distributions[Amount])

    Hope this helps!

      No, unfortunately this does not help.  I tried this and still am receiving the Ranking of 1 for Household ID.

        Can you create a data sample?
