Calculate Unique Visits
Data table linked to a Key and Date Dimension: 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 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]))
Pat
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.
