I am attempting to write a calculate measure in Power BI desktop that determines if a person was enrolled in program during a given month. When a person is enrolled, the Enrolled Date is set, and the Disenrolled Date = null. When they are disenrolled, the disenrolled date is set. Since a person can enroll more than once, I cant just set a flag to indicate enrolled.
I put together some syntax from other posts that looks like this:
Active Patients = CALCULATE (Countrows(PatientHistory),FILTER(PatientHistory,(PatientHistory[tkh_EnrolledDate]<=LASTDATE('Calendar'[Date])&&[tkh_DisenrolledDate]>=FIRSTDATE('Calendar'[Date])))||(PatientHistory[tkh_EnrolledDate]<=LASTDATE('Calendar'[Date])&&[tkh_DisenrolledDate]= BLANK() )))
The editor is erroring on the last ), but I suspect it is something else. Any ideas?
Thanks in advance.
Solved! Go to Solution.
You have an extra closing ) before the || operator
You have 3 there when they should be 2 ))

thank you, That fixed the syntax.
Since this table can have records that have enrolled date and disenrolled date with enrolled date, both, or none populated, I wanted to restrict the results set to only those that have ever been enrolled.
I created a calculated column that set a flag if Enrolled Date <> Blank() and used that as a filter in the visual. Working now.
