Aggregated roles, also known as custom roles, aggregate multiple predefined roles belonging to an application. An aggregated role can contain other aggregated roles. For example, a Shared Services Administrator or Provisioning Manager can create an aggregated role that combines the Planner and View User roles of a Planning application. Aggregating roles can simplify the administration of applications that has several granular roles. Global Shared Services roles can be included in aggregated roles. You cannot create an aggregated role that spans applications or products.
