I am attempting to create a calculated field that will return to me the last 90 days worth of a measure.
I know that you can do this using the relative date dimension, however, if I rely on the relative date field, it limits me from putting different measures on the shelf that do not need the last 90 days field.
To clarify, I provide a weekly executive report that has several different measures with different time dimensions.
Last week installs
Last week deinstalls
Customers Not Serviced in more than 30 Days
Stores with multiple stockouts in 90 days
As you can see, there are 4 different measures here with 3 different time dimensions.
I have figured out the rest of them by creating a calulated field, but am having trouble and need help with the 90 days calculation.
