Count Values from other Table only once

Hello - i ran into a Problem in Power BI after trying a lot.

I have a big Table containing Appointments.

The Start- and End- Times are indicated by numbers from 0 to 95 (for each 15-Minute Block from 00:00 to 23:45).

 

Columns:

Date

StartTime

EndTime

ExamRoom

Doctor

and others...

 

I want to calculate the Duration of the daily Worktime for each Doctor without counting his booking in two ExamRooms at the same timeslot twice.

 

Groupby / SUMX counts every booking in every room - thats where i got stuck.

Anybody has an Idea?

I already created a Table with the TimeIndexes from 0 to 95 but i can't figure out

  • how to count for each day
  • for each timeslot
  • if there is one or more appointments for the doctor in the appointments-table
  • and counting this as 1 or 0
Need Help

    You will need to define which value (or calculation) in a record will flag the surviving record when there is more than 1 record per doctor booking per day.

     

    This definition is needed up front to then best decide how to implement the best filter.
