Dax Formula calculations

[Polar_A]

Hi

I need some help please. My Dax measures counts are not working dependently to one another. i have done a male and female count, but it is only taking to account either male or either female and not giving me a total count. Its as if it has taken the first value in the source whereas I want the total value.

Herre are some of my Dax measures that I used:

MaleCount =

CALCULATE(

    COUNTROWS(Patients),Patients[Gender] = "Male",

    FILTER(ALL(Prescriptions),Prescriptions[Therapy] = MAX(Prescriptions[Therapy])),

    FILTER(ALL(Patients),Patients[Referring Establishment] = MAX(Patients[Referring Establishment])))

FemaleCount =

CALCULATE(

    COUNTROWS(Patients),Patients[Gender] = "Female",

    FILTER(ALL(Prescriptions),Prescriptions[Therapy] = MAX(Prescriptions[Therapy])),

    FILTER(ALL(Patients),Patients[Referring Establishment] = MAX(Patients[Referring Establishment])))

Average Age = CALCULATE(

    AVERAGE(Patients[Age]),

    FILTER(ALL(Prescriptions),Prescriptions[Therapy] = MAX(Prescriptions[Therapy])),

    FILTER(ALL(Patients),Patients[Referring Establishment] = MAX(Patients[Referring Establishment])))

Registered =

CALCULATE(

    COUNTROWS(Patients),Therapy[Created On],

    FILTER(ALL(Prescriptions),Prescriptions[Therapy] = MAX(Prescriptions[Therapy])),

    FILTER(ALL(Therapy),Therapy[NHS/Hospital] = MAX(Therapy[NHS/Hospital])),

    FILTER(ALL(Patients),Patients[Referring Establishment] = MAX(Patients[Referring Establishment])))

Thank you

Hi @Polar_A ,

Base on your description, it seems like the total values of FemaleCount and MaleCount are incorrect. You can create another two new measures as below and replace the measure [MaleCount] and [FemaleCount] with these two new measures.

New_FemaleCount =
SUMX (
    VALUES ( Prescriptions[Therapy] ),
    SUMX ( VALUES ( Patients[Referring Establishment] ), [FemaleCount] )
)

New_MaleCount =
SUMX (
    VALUES ( Prescriptions[Therapy] ),
    SUMX ( VALUES ( Patients[Referring Establishment] ), [MaleCount] )
)

If the above ones can't help you figure out, please provide some raw data in your tables(exclude sensitive data) with Text format and your expected result with backend logic and special examples. It would be helpful to find out the solution. You can refer the following link to share the required info:

And 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.
