The document discusses Oracle Fusion enterprise structures. It defines key concepts like enterprise, division, legal entity, and business unit. An enterprise captures a company name and headquarters. Structures are implemented through legal entities, divisions/business units, and departments. Divisions segregate businesses and business units perform functions that can be managed together. Legal entities define registered companies. Departments track employees. Reference data sets share common data like jobs, grades, and locations across business units. The Enterprise Structures Configurator tool guides users to set up divisions, entities, units, and reference data based on questions about an enterprise.
