As a Tableau newbie I have what I imagine is a very basic question-
I am trying to create a calculated metric called "AppointmentVolume". I would like to just do a countd on an attribute called ConfirmationNumber (dimension) where another dimension, "IsCancelled" is 'false'. Both attributes are in the same table
I have tried a number of different statements, and all show up as 'invalid'
I thought it would be something like:
countd(ConfirmationNumber) WHERE (IsCancelled='False')
Any tips would be greatly appreciated- its driving me nuts!
