Parameters are gathered during the data collection process. These parameters are the basis on which other report objects are built, such as dimensions, measures, and segments. Using Account Settings, you can give these parameters user-friendly names and customize how they are displayed. For example, instead of searching for the query parameter data_wt_mc_id, you can name it Marketing Campaign ID and add it to the Campaigns category.
NOTE: You must be granted access to Account Settings by your account’s administrator to manage parameters.
To learn more, see Managing Parameters in the product help section for Account Settings.
