Hi
I am fairly new to DAX and am having a problem doing an advance calculation. Without going into the full-blown explanation of cohort Surval Rate calculation, I have tried to focus on a small using which I think stems from an ALLSELECT statement I use.
If someone can anyone please tell me what I am going wrong I would be extremely grateful!
The table below explains my issue. In summary, the measure GC2 works but I have a problem with the measure GC3. I see this is because the measure X3 returns ZEROs in each row and not 0.816 in each row. However, the calculation works in measure X2
The formulas are:
GC2=X2* Y2
GC3=X3* Y3
Where X2 and X3 are generated by the following formulas
X2 = CALCULATE([GC1],
FILTER(Allselected(SurvivalRate),
SurvivalRate[GradeCode]=1))
and
X3 = CALCULATE([GC2],
FILTER(Allselected(SurvivalRate),
SurvivalRate[GradeCode]=2))
You can open this link to my example file which I have published on my Onedrive account, but this table attempts to explain the issue.
Solved! Go to Solution.
@CrudenBoy What is it you are ultimately trying to acheive? Do GC0, GC1, etc actually need to be in separate columns? I'm wondering if you could use the EARLIER function to create a series of calculated columns in a GradeCode table that has each grade code listed once?

Iterators might also help to lock in the row and table context that each measure needs to calculate within, rather than how they are now which is floating across the data model and recalculating depending on how you setup your table.

EARLIER and Iterators might help you get what you need.

Thank you very much for your feedback @Anonymous @AllisonKennedy and @vivran22 and let me apologise for my limited description of my problem. Alison's post was very useful as it made me read up about the filter context and row context and I have managed to make progress.

Hello @CrudenBoy ,
Can you explain the logic behind the calculation for X2, X3, Y2 & Y3 along with example?
Cheers!
Vivek
