Help with DAX
DAX measure to show which patient has completed a 'cosmetic' treatment within 4 weeks of completing an 'examination' treatment.
E.g. an examination on the 01/02/2023 and cosmetic on the 10/02/2023 would be marked as 1 whereas if the examination happened on 01/02/2023 and 'cosmetic' on the 20/03/2023, it would be marked as 0. A patient may also have a future examination and future cosmetic so it should pick up those as well.
Patientkey is in 'treatments' table but 'patient name' is from the 'patients' table. Rest of the columns are in 'Treatments'

CALCULATE(
SUM('Treatments'[IsCosmeticWithin4Weeks]),
ALLEXCEPT('Treatments', 'Treatments'[PatientKey])
)last apply the flag 0 or 1 condition on table. as below one more measure create it.PatientCompletedCosmeticWithin4Weeks =
