Help with RANKX - Returning 1 for All Values
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] )
