Hi, I am linking power pivot to a table of 220 million rows. I want to find the first time an ID appears in the data set.
In doing so I would like to create a new measure by using the following formula:
=N(countifs(Adrian_data[DeviceID],Adrian_data[DeviceID])=1)). The problem I am having is how do you tell Dax that the Device Id that I want is in the entire column. Essentially I want to use the column as a range.
How do you identify a complete column as a range?
