Summary
The Organizational report is located within TDNext, in the Analysis application, under the Standard Reports section. This report displays the hierarchy of people within your organization. People who have other resources reporting to them will have an expand/collapse button by their name. Also displayed in this report are each person's title, functional roles (primary functional role will be denoted by *), whether they are an employee or not and whether or not they are active. Each person's name is a link to their user profile.
Note that running the report without a Reports To person selected equates to running the report for people who report to nobody.
