You can use hierarchies to structure your data to track your telecom use or spend across different groups and functions of your organization for more informed reporting and analysis: 

• Review monthly telecom spend by business unit, division, department, group, or other segment of your organization; assign costs among groups that share telecom services.
  
  
• Use a hierarchy and its levels like data filters for your reports (in addition to standard and custom filters).
  
  
• Create multiple hierarchies to test and compare different reporting scenarios.
   

A hierarchy mirrors the structure of your organization—business units, regional offices, retail outlets, cooperatives, departments, and other reporting groups. The nodes and sub-nodes of a hierarchy form a tree structure, connected in parent-child relationships, representing your organization’s various groups. Split services between nodes to assign costs across multiple groups that share a service.

You can set a hierarchy you create as private (seen only by the person who created the hierarchy) or public (seen by all users in your organization).
