FND Role Hierarchy
Description:
User Management (UMX) role hierarchy to manage role-based access control (RBAC). When run for a specified role, the report shows all hierarchies that contain or lead to inheriting that role.
Parameters
Role Name, Role Code
Used tables
umx_role_categories_v, wf_role_hierarchies, wf_roles, fnd_application_vl
Categories
Dependencies
If you would like to try one of these Oracle EBS SQLs without having Blitz Report installed, note that some of the reports require functions from utility package xxen_util.

Executive Summary
The FND Role Hierarchy report visualizes the structure of User Management (UMX) roles, specifically focusing on role inheritance. It allows administrators to understand how roles are nested and how permissions flow from child roles to parent roles within the Role-Based Access Control (RBAC) model.
Business Challenge
In complex RBAC implementations, roles often inherit permissions from other roles. As these hierarchies grow deep, it becomes difficult to trace exactly why a user has a certain permission or to predict the impact of changing a child role. Lack of visibility into this hierarchy can lead to unintended privilege escalation or redundant role definitions.
The Solution
This report unravels the role hierarchy. When run for a specific role, it shows all the hierarchies that contain or lead to inheriting that role. This provides a clear lineage of access, helping administrators:
- Validate the design of their role hierarchy.
- Ensure that role inheritance is working as intended.
- Clean up unused or redundant hierarchy paths.
Technical Architecture
The report utilizes the Workflow directory service tables, specifically wf_role_hierarchies and wf_roles, which underpin the UMX security model in Oracle EBS.
Parameters & Filtering
- Role Name: The display name of the role to analyze.
- Role Code: The internal system name of the role.
Performance & Optimization
The report is efficient for analyzing specific roles. Querying the entire hierarchy of a large system without filters may produce a large dataset due to the many-to-many nature of role relationships.
FAQ
Q: Is this related to Responsibilities? A: Yes, in the UMX model, responsibilities can be assigned to roles, and roles can be assigned to users. This report focuses on the relationship between the roles themselves.
Q: Can I see which users are assigned to these roles? A: This report focuses on the role structure. Use the FND Roles or FND User Roles reports to see user assignments.
Oracle E-Business Suite Reporting Library
We provide an open source Oracle EBS SQLs as a part of operational and project implementation support toolkits for rapid Excel reports generation.
Blitz Report™ is based on Oracle EBS forms technology, and hence requires minimal training. There are no data or performance limitations since the output files are created directly from the database without going through intermediate file formats such as XML.
Blitz Report can be used as BI Publisher and Oracle Discoverer replacement tool. Standard Oracle BI Publisher and Discoverer reports can also be imported into Blitz Report for immediate output to Excel. Typically, reports can be created and version tracked within hours instead of days. The concurrent request output automatically opens upon completion without the need for re-formatting.
The Filters, Columns, Rows and Values fields are used to create and deliver the data in pivot table format with full drill down to details.

The Excel template upload functionality in Blitz Report allows users to create their own layouts by uploading an Excel template with additional sheets and charts, automatically refreshed when the report runs again. This allows to create custom dashboards and more advanced visualizations of report data.

You can download and use Blitz Report free of charge for your first 30 reports.
The installation and implementation process usually takes less than 1 hour; you can refer to our installation and user guides for specific details.
