Configure a Connection and Data View in Customer Journey Analytics
Once you successfully ingest historical data and/or configure data collection to Adobe Experience Platform, you can Create a connection to allow Customer Journey Analytics to reference that data.
Use the connection to create one or more Data Views for use in Analysis Workspace.
Create reports
After configuring dimensions and metrics within a Data View, you can begin using Analysis Workspace to generate the desired reports. See Report on Google Analytics data in Customer Journey Analytics.
