Once your organization has established and implemented a data layer on your site, you can map data layer objects to data elements within tags.
Data elements are components in Adobe Experience Platform Data Collection that you can use across the tool. You can assign variable values in the Adobe Analytics extension using data elements.
Log in to Adobe Experience Platform Data Collection using your AdobeID credentials.
Click the desired tag 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.
