Once your organization has established and implemented a data layer on your site, you can map data layer objects to data elements within Launch.
Data elements are components in Launch that you can use across the tool. You can assign variable values in the Adobe Analytics extension using data elements.
Go to Adobe Experience Platform Launch and log in if prompted.
Click the desired Launch property.
Click the Data Elements tab, then click Add Data Element.
Under the Extension dropdown, select Core.
Map data elements to Analytics variables: Assign data elements to Analytics variables so you can use them as dimensions in Analysis Workspace.
