Overview

The view IGS_CO_S_PER_LTR is a database object within the Oracle E-Business Suite (EBS) Student System module, specifically designated as obsolete. Its primary function is to provide a filtered, organization-specific view of system-generated correspondence letters associated with a person (typically a student). The view acts as a security layer over the underlying base table, IGS_CO_S_PER_LTR_ALL, by enforcing Multi-Org Access Control (MOAC). It restricts data visibility to the operating unit (ORG_ID) context established in the user's session via the CLIENT_INFO application context, ensuring users only access letter data pertinent to their assigned organization.

Key Information Stored

The view's columns represent the core attributes required to track and manage system-produced letters for individuals. Key columns include PERSON_ID, which links to the student or person; CORRESPONDENCE_TYPE and LETTER_REFERENCE_NUMBER, which classify and uniquely identify the letter template or batch; and SEQUENCE_NUMBER for ordering. The ORG_ID column is central to the view's security filter. Standard EBS audit and process columns (CREATED_BY, CREATION_DATE, LAST_UPDATED_BY, LAST_UPDATE_DATE, REQUEST_ID, PROGRAM_ID, PROGRAM_APPLICATION_ID, PROGRAM_UPDATE_DATE) are present to track changes and the concurrent programs that initiated them. The ROW_ID column exposes the physical ROWID from the underlying table for potential performance optimization in queries.

Common Use Cases and Queries

This view is primarily used for reporting and inquiry purposes related to student communications. A common scenario involves auditing all system letters generated for a specific student within the user's current operating unit. A typical query pattern would leverage the security filter implicitly. For example:

  • Retrieving letter history for a student: SELECT correspondence_type, letter_reference_number, creation_date FROM igs_co_s_per_ltr WHERE person_id = 123456 ORDER BY creation_date DESC;
  • Identifying letters of a specific type generated by a particular concurrent request: SELECT person_id, letter_reference_number FROM igs_co_s_per_ltr WHERE correspondence_type = 'ADMISSION' AND request_id = 100100;

Due to the module's obsolete status, direct operational use in customizations or new developments is strongly discouraged. Any queries should be for diagnostic or historical reporting only.

Related Objects

The view has a direct and singular dependency on the base table IGS_CO_S_PER_LTR_ALL, from which it selects all columns and applies the MOAC WHERE clause. Given its purpose in the Correspondence (CO) sub-module, it is logically related to other tables defining correspondence types (IGS_CO_TYPE), letter parameters, and the core person/student tables (IGS_PE_PERSON). However, the provided metadata confirms this specific object was "Not implemented in this database," indicating it may exist as a placeholder or remnant in standard documentation but not as a physically instantiated object in all EBS environments. This necessitates verification of the view's existence via USER_VIEWS before attempting to reference it in any code.
