The Customer journey widget, on the customer composite, displays the most common customer activities in a customer timeline view. Configure the events source for the customer timeline, and configure additional events to track, if required.
By default, the customer timeline pulls events from the Pega Customer Service work tables, which include only customer service events. If that is the source that you want to use for the customer timeline, select the events work table for your application.
If you have a license for Decisioning and you enable that feature, then the customer timeline pulls events from the Apache Cassandra data store, which includes customer service, sales automation, and marketing events.
