The Configuration menu allows users with the necessary rights to configure the types and sub-types of Action Categories and Action Sources that can be recorded in the system (refer to figures Sample Action Categories and Sample Action Sources ). The configuration takes the form of a hierarchy tree. Additional types can be created by right-clicking on an existing type and selecting Add Sibling. Additional subtypes can be entered by right-clicking on an existing type and selecting Add Child, or by right-clicking on an existing subtype and choosing Add Sibling. Types and subtypes can also be edited and deleted using the right-click menu.
