Dear Techie,
I have two fact tables (Census & Events) and they are connected to a common dimensions like Patient, Date. I want to create a measure that will give the date difference between Admission date (Census Fact) and Event date (Event Fact) in days.
Relationships:
Census Date
Census Date*:1 Date
Event Date
Event Date*:1 Date
Census Patient
PatientKey PatientKey
Event Patient
PatientKey PatientKey
Example:
When I add Event Date and Admission Date for a particular patient, this is how the report looks. I want to add a measure next to this that should give the difference in days
I have tried many options but none is working. Can anyone please help me on this?
Thanks,
Latheesh

@parry2k As suggested, I have added the details. Please let me know if you required anymore details.
@latheesh89 so you are looking for difference between event date and admission date?
add a new columna as below
# of Days = DATEDIFF( Table[Admission Date], Table[Event Date], DAY )
