Ensuring Dates are factored into your Dax Command

[Karolina411]

Hello Power Bi Aces:  So...I used this Dax function: 

ReAdmit of Post_Admit = CALCULATE(DISTINCTCOUNT(PrePostAdmits[DurableKey]),FILTER(ALL(PrePostAdmits),PrePostAdmits[Readmit<30Days]=1 ||PrePostAdmits[PostAdmit]= 1))  where I have 4 different dates in MY table and am connecting my START date (when patient started in Case Management) and I am having to calculate the admission rates based on less than 30 days.  That being said the overall calculation works:  

%Total Readmits = [Readmission]/[Patient Count]

but when I break them down as in the first DAX formula with 2 factors and use the SAME denomintor:

%ReadmitsofPostAdmits = calculate([ReAdmit of Post_Admit]/[Patient Count]) (new Numerator ) it does not submit to the the date dimension and break it out among dates.  Should I change this formula:CALCULATE(DISTINCTCOUNT(PrePostAdmits[DurableKey]),FILTER(ALL(PrePostAdmits),PrePostAdmits[Readmit<30Days]=1 ||PrePostAdmits[PostAdmit]= 1))  - the number it outputs is correct but not across the dates?

Hi, @Karolina411 ;

You could try it.

ReAdmit of Post_Admit =
CALCULATE (
    DISTINCTCOUNT ( PrePostAdmits[DurableKey] ),
    FILTER (
        ALL ( PrePostAdmits ),
        YEAR ( [date] ) = YEAR ( MAX ( 'table'[date] ) )
            && PrePostAdmits[Readmit<30Days] = 1
            || PrePostAdmits[PostAdmit] = 1
    )
)

Here 'table' could change to this table's name.

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

@Karolina411 , I think you need measure similar to what I have discussed in HR Blog

Thank you.  I was planning to go toward this much more complex route but why does my same formula (

work for my initial % calc: 

%Total Readmits = [Readmission]/[Patient Count] - works

%ReadmitsofPreAdmits = [ReAdmit of Pre_Admit]/[Patient Count] does not work and I get infinity error

(

ReAdmit of Post_Admit = CALCULATE(DISTINCTCOUNT(PrePostAdmits[DurableKey]),FILTER(ALL(PrePostAdmits),PrePostAdmits[Readmit<30Days]=1 ||PrePostAdmits[PostAdmit]= 1))

I think the Numerator for ReAdmit of Post_Admit is not playing nice with my denominator.  Any suggestions are appreciated as I need to learn how to add Date Dimensions to my CALCULATE(DISTINCTCOUNT(PrePostAdmits[DurableKey]),FILTER(ALL(PrePostAdmits),PrePostAdmits[Readmit<30Days]=1 ||PrePostAdmits[PostAdmit]= 1))     How to add in Date Dim?
