Triangle object relationships
Within the triangle, the top
(parent 1) and bottom
(child) object types are
non-recursive. The middle
(parent 2) object type is recursive (such as Sub-Process). For more
information about recursive objects, see Recursive object levels.
A triangle relationship that includes two recursive object types is not supported.
For example, a report author has a requirement to create a Risk report that allows business users to assess risks associated with various processes and sub-processes within the company.
To provide the report author with easier reporting capability in the framework model, you could configure a triangle relationship between the non-recursive child Risk object and its two related parents: a non-recursive parent Process object and a recursive parent Sub-Process object type, as shown in Figure 1.

The path between the objects that forms a triangle relationship must be reflected in a namespace within the reporting framework. For example, a namespace might have the following object type hierarchy configured for Business Entity, Process, Sub-Process, and Risk object types:
SOXBusEntity|SOXProcess,SOXProcess|SOXSubprocess,SOXSubprocess|SOXRisk
SOXBusEntity|SOXProcess,SOXProcess|SOXSubprocess,SOXProcess|SOXRisk,SOXSubprocess|SOXRisk
Without the configured triangle, the report author would need to use advanced techniques, which might not perform as well to accomplish this task.
