The IGS_HE_USR_RT_CL_FLD table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical data structure within the Higher Education (HE) module, specifically designed to manage user-defined rating class fields. This table plays a pivotal role in customizing and extending the functionality of the Student Systems module, allowing institutions to tailor the system to their specific academic and administrative requirements. Below is a detailed analysis of its purpose, structure, and significance in Oracle EBS.

Purpose and Functional Context

The IGS_HE_USR_RT_CL_FLD table is part of the Oracle Higher Education (HE) product family, which is built on the Oracle EBS framework. It stores metadata and configuration details for user-defined fields (UDFs) associated with rating classes. Rating classes are used to categorize and evaluate academic or administrative data, such as student performance, course ratings, or institutional benchmarks. By leveraging this table, institutions can define custom fields to capture additional attributes or metrics that are not covered by standard Oracle EBS functionality.

Table Structure and Key Columns

The table typically includes the following key columns, though the exact schema may vary slightly between EBS 12.1.1 and 12.2.2:
  • RATING_CLASS_ID: A foreign key linking to the parent rating class definition.
  • FIELD_NAME: The name of the user-defined field, which must adhere to Oracle naming conventions.
  • FIELD_TYPE: Specifies the data type of the field (e.g., VARCHAR2, NUMBER, DATE).
  • FIELD_LABEL: A descriptive label for the field, often used in UI displays.
  • REQUIRED_FLAG: Indicates whether the field is mandatory for data entry.
  • DISPLAY_SEQUENCE: Determines the order in which fields appear in forms or reports.
  • CREATED_BY and LAST_UPDATED_BY: Audit columns tracking user modifications.

Integration with Other Modules

The IGS_HE_USR_RT_CL_FLD table interacts with several other Oracle EBS components, including:
  • IGS_HE_RT_CLS: The master table for rating classes, which defines the parent entities for these custom fields.
  • IGS_HE_USR_RT_FLD_VAL: Stores actual values for the user-defined fields, linked via RATING_CLASS_ID and FIELD_NAME.
  • Oracle Flexfields: In some implementations, UDFs may leverage Descriptive Flexfields (DFFs) for additional configurability.

Technical Considerations

In Oracle EBS 12.2.2, the table benefits from the underlying architectural improvements, such as Online Patching (ADOP) and enhanced performance optimizations. However, administrators must ensure that customizations involving this table comply with Oracle's supportability guidelines. For example, direct DML operations on the table should be avoided in favor of approved APIs or screen-based configurations.

Customization and Extensibility

The IGS_HE_USR_RT_CL_FLD table exemplifies Oracle EBS's extensibility. Institutions can:
  • Add new fields to support localized accreditation requirements.
  • Modify existing fields to align with changing academic policies.
  • Integrate with external systems by exposing these fields via web services or APIs.

Conclusion

The IGS_HE_USR_RT_CL_FLD table is a cornerstone of the Oracle Higher Education module, enabling institutions to adapt the EBS platform to their unique needs. Its design reflects Oracle's commitment to configurability while maintaining data integrity and system performance. Proper utilization of this table requires a thorough understanding of both the technical schema and the functional workflows it supports within the Student Systems domain.
