Classifications are created by grouping (classifying) granular
data from a source report. For example, you might want to analyze display ads,
but they are mixed with email, partner, text ad, and social media campaigns.
You can create groups so that you can analyze them separately.
Important: On May 10, 2018, we will begin limiting the
functionality of date-enabled and numeric classifications. These classification
types will be removed from the Admin and Classification Importer interfaces.
From that date on, no new date-enabled and numeric classifications can be
added. Existing classifications can still be managed (uploaded to, deleted)
through the standard classification workflow, and will continue to be available
