The POR_ITEM_ATTRIBUTE_VALUES table in Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 is a critical repository for storing item attribute values associated with procurement and purchasing documents. This table plays a pivotal role in the iProcurement module, enabling organizations to define and manage custom attributes for requisition lines, purchase orders, and other procurement-related transactions. Below is a detailed technical breakdown of its structure, functionality, and integration within Oracle EBS.

Table Overview

The POR_ITEM_ATTRIBUTE_VALUES table is part of the Purchasing Open Requisitions (POR) schema and stores extensible attribute values assigned to items in procurement documents. It supports flexible attribute definitions, allowing organizations to capture additional metadata beyond standard Oracle Inventory or Purchasing attributes. This table is primarily used in conjunction with the POR_REQUISITION_LINES_ALL and PO_LINES_ALL tables to enhance procurement workflows.

Key Columns and Structure

The table includes the following critical columns:
  • ATTRIBUTE_VALUE_ID: Primary key, uniquely identifying each attribute value record.
  • DOCUMENT_TYPE: Specifies the document type (e.g., "REQUISITION," "PURCHASE ORDER").
  • DOCUMENT_HEADER_ID: Foreign key linking to the document header (e.g., PO_HEADERS_ALL or POR_REQ_HEADERS_ALL).
  • DOCUMENT_LINE_ID: Foreign key referencing the document line (e.g., PO_LINES_ALL or POR_REQUISITION_LINES_ALL).
  • ATTRIBUTE_NAME: Name of the custom attribute (e.g., "Project Code," "Department").
  • ATTRIBUTE_VALUE: The actual value assigned to the attribute.
  • CREATED_BY, CREATION_DATE, LAST_UPDATED_BY, LAST_UPDATE_DATE: Standard Oracle audit columns.

Functional Role in Procurement

The table enables organizations to:
  1. Extend Procurement Data: Capture additional item-level details (e.g., cost center, budget code) not natively supported in standard Oracle tables.
  2. Support Approval Workflows: Custom attributes can trigger approval rules in Oracle Approvals Management (AME).
  3. Enhance Reporting: Facilitate granular reporting on procurement activities using custom attributes.
  4. Integrate with External Systems: Custom attributes can map to fields in third-party systems via Oracle Integration.

Integration with Other Modules

The POR_ITEM_ATTRIBUTE_VALUES table interacts with:
  • Inventory (INV): Attributes may reference item master data (MTL_SYSTEM_ITEMS_B).
  • General Ledger (GL): Custom financial attributes (e.g., account segments) can link to GL tables.
  • Projects (PA): Project-related attributes may integrate with PA_PROJECTS_ALL.

Technical Considerations

  • Indexing: Optimal performance requires indexes on DOCUMENT_HEADER_ID, DOCUMENT_LINE_ID, and ATTRIBUTE_NAME.
  • Data Volume: High-transaction environments may require partitioning.
  • Security: Attribute access can be controlled via Oracle Function Security.

Customization and Extensions

Organizations often extend this table by:
  • Adding application-specific attributes via descriptive flexfields (DFFs).
  • Creating APIs to bulk-load attribute values during integrations.
  • Developing custom PL/SQL triggers to validate attribute logic.

Conclusion

The POR_ITEM_ATTRIBUTE_VALUES table is a cornerstone of Oracle iProcurement’s extensibility, enabling tailored procurement processes. Its design supports complex attribute management while maintaining integration with core EBS modules. Proper implementation ensures alignment with organizational procurement policies and reporting requirements.
