The Lists and Profiles page is available in Process Manager under Admin > Data.
See Data tab.
Profiles let you categorize data by adding customizable fields to the default profile reference types. Profiles let you sort data in Process Manager. Profiles are similar to custom data types. They are a way of classifying data for reporting and filtering.
Make a new profile when you have a process that creates or tracks the object that has the same attributes each time. This can be a computer object, a ticket object, or a Workflow task object. The profile populates with the data that is captured each time the process runs.
