With date intelligence measures developed for the current and prior periods, growth or variance measures can be added to the dataset, comparing the two values. In the following example, a year-over-year (YOY) and a year-over-year year-to-date (YOY YTD) measure have been created based on the current year and prior year measures from the preceding section:
Internet Net Sales (YOY) = [Internet Net Sales (CY)] - [Internet Net Sales (PY)] Internet Net Sales (YOY YTD) = [Internet Net Sales (YTD)] - [Internet Net Sales (PY YTD)]
Finally, growth percentage measures can be added, which express the variance between the current and prior period measures as a percentage of the prior period. The following measures ...
