Help with RANKX - Returning 1 for All Values

[Anonymous]

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.

Hi @Anonymous 

Can you create a data sample?
