RICE components refer to Reports, Interfaces, Conversions, and Enhancements that are developed to satisfy additional functional requirements beyond an Oracle application's core functionality during implementation. Reports are developed using tools like SQL and Report Builder based on user requirements. Conversions upload one-time data like supplier records from Excel or legacy systems into Oracle apps tables. Interfaces regularly transfer data between Oracle apps and other systems, while enhancements personalize forms based on user needs. RICE components involve creating new reports, interfaces to other systems, data conversion programs, and enhancements to existing functionality.
