Calculate Unique Visits

Data table linked to a Key and Date Dimension:

VolumeDemo.png

I want to calculate a 1 the first time a Patient ID appears per service date.

If a Patient ID appears multiple times on a particular service date, I only want to calculate a 1 the first time it appears.
Is there an easy way to do this as a calculated column?

I ended up concatenating Pat_ID and Orig_Service_Date and then doing a Distinct Count of that

You should probably do this as a measure and not a column.  Here is one way to do it, if I understand your scenario correctly.

 

Unique Visits = COUNTROWS(SUMMARIZE(Data, Data[Pat_ID], Data[Orig_Serv_Date]))

Can't be a measure.

Must be a calculated column as there are about 10 other columns not shown that the # has to interact with.
