Overview

The table IGS_PS_USEC_REF is a core data structure within the Oracle E-Business Suite's now-obsolete Student System (IGS). Its primary function is to establish and maintain the relationships between Unit Sections and their associated Unit Section Reference Codes. This table acts as a junction entity, enabling the complex linking of specific course offering components (unit sections) to standardized reference codes that may categorize or describe them for administrative, reporting, or academic planning purposes. It is important to note that the ETRM metadata explicitly states this table is "Not implemented in this database" for the documented instance, indicating it may be a legacy or placeholder object in certain EBS 12.1.1/12.2.2 deployments.

Key Information Stored

While specific column datatypes are not provided in the metadata, the documented primary and foreign keys reveal the critical data elements. The table's unique identifier is the UNIT_SECTION_REFERENCE_ID, which serves as the primary key (IGS_PS_USEC_REF_PK). The two principal foreign keys define its relationships: the UOO_ID links to the IGS_PS_UNIT_OFR_OPT_ALL table (Unit Offering Option), thereby connecting the reference to a specific unit section instance. The SUBTITLE_ID links to the IGS_PS_UNIT_SUBTITLE table, potentially associating a descriptive subtitle with the section reference. The table also enforces a unique key (IGS_PS_USEC_REF_UK) on the UOO_ID column, suggesting a one-to-one or one-to-many relationship constraint between a unit section and its reference records.

Common Use Cases and Queries

This table would be central to queries that need to retrieve or validate the reference codes assigned to active unit sections. A typical use case involves generating reports for academic administration that list all unit sections alongside their official reference classifications. Sample SQL would involve joining IGS_PS_USEC_REF to the unit offering and reference code tables. For instance, to find all reference codes for a given unit section, one might query: SELECT ref_cd.* FROM igs_ps_usec_ref usec_ref JOIN igs_ps_usec_ref_cd ref_cd ON usec_ref.unit_section_reference_id = ref_cd.unit_section_reference_id WHERE usec_ref.uoo_id = :p_uoo_id;. Given its "Obsolete" status, its primary use in later EBS versions would likely be for data migration reference or supporting legacy customizations.

Related Objects

The IGS_PS_USEC_REF table sits at the intersection of several key Student System entities, as defined by its foreign key relationships:

  • Referenced By (Child Tables):
  • References (Parent Tables):
    • IGS_PS_UNIT_OFR_OPT_ALL: Linked via UOO_ID. This defines the specific unit section.
    • IGS_PS_UNIT_SUBTITLE: Linked via SUBTITLE_ID. This provides an optional descriptive subtitle.

These relationships form a critical part of the data model for managing unit section metadata, ensuring referential integrity between a section, its descriptive attributes, and its assigned classification codes.
