In Oracle Planning 2024, Navigation Flows can be customized to tailor the user interface and experience based on specific categories. The three customization categories supported are Role, Group, and Global:

A. Role: Navigation Flows can be customized for specific user roles (e.g., Planner, Administrator), allowing different layouts or access to cards based on job functions.

C. Group: Customization can be applied to user groups, enabling administrators to assign tailored navigation flows to predefined sets of users based on their team or department.

E. Global: Global customization applies to all users across the application, serving as the default navigation flow unless overridden by Role or Group settings.

B. User: This is incorrect because Oracle Planning does not support navigation flow customization at the individual user level—customizations are broader, targeting roles or groups.

D. Artifact: This is incorrect because "Artifact" refers to application components (e.g., forms, rules) managed in migration, not a category for navigation flow customization.

The Oracle documentation confirms that Role, Group, and Global are the three levels at which navigation flows can be customized, providing flexibility in how users interact with the Planning application.
