The ICX_POR_ORACLE_ITEM_SUBTABLE is a critical table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2, primarily associated with the iProcurement (iProc) module and the Procurement Online Requisition (POR) functionality. This table serves as a subordinate or child table that stores supplementary item-related data, often linked to requisition lines or catalog items, enabling extended attributes, configurations, or additional metadata for procurement transactions. Below is a detailed analysis of its purpose, structure, and integration within Oracle EBS.

Purpose and Functional Context

The ICX_POR_ORACLE_ITEM_SUBTABLE table is designed to support complex procurement scenarios where standard item attributes (stored in tables like PO_REQUISITION_LINES_ALL or MTL_SYSTEM_ITEMS_B) are insufficient. It captures extended item details, such as:

  • Configurable Item Data: For items with dynamic attributes (e.g., color, size) in punchout catalogs or internal setups.
  • Additional Metadata: Supplemental information like supplier-specific notes, compliance details, or user-defined fields.
  • Integration Data: Temporary or intermediate values during requisition import/export processes.

This table is often referenced in conjunction with the ICX_POR_ITEMS_INTERFACE or ICX_CAT_ITEMS_V views, facilitating seamless data flow between iProcurement and other EBS modules like Inventory (INV) or Purchasing (PO).

Table Structure and Key Columns

While the exact schema may vary slightly between EBS 12.1.1 and 12.2.2, the table typically includes the following key columns:

Column Name Data Type Description
ITEM_ID NUMBER Foreign key linking to the parent item record (e.g., in MTL_SYSTEM_ITEMS_B).
SUB_TABLE_ID NUMBER Primary key identifier for the subtable entry.
ATTRIBUTE_NAME VARCHAR2 Name of the extended attribute (e.g., "CONFIG_CODE").
ATTRIBUTE_VALUE VARCHAR2 Value assigned to the attribute.
CREATION_DATE DATE Timestamp when the record was created.
LAST_UPDATE_DATE DATE Timestamp of the last modification.

Additional columns may include context-specific fields like ORG_ID (for multi-org support) or REQUISITION_LINE_ID for requisition linkage.

Integration with Oracle EBS Modules

The ICX_POR_ORACLE_ITEM_SUBTABLE integrates with several EBS components:

  • iProcurement: Stores item configurations during requisition creation, especially for punchout catalogs or complex items.
  • Purchasing (PO): Passes extended attributes to purchase orders via the PO_REQUISITION_INTERFACE table.
  • Inventory (INV): References item master data while preserving supplemental details not captured in MTL_SYSTEM_ITEMS_B.

Customization and Extensibility

In implementations requiring custom item attributes, this table can be extended or leveraged via Oracle's Open Interface Tables or PL/SQL APIs. For example:

  • Custom workflows may query this table to validate item configurations.
  • Data migration scripts often populate it during catalog item imports.

Conclusion

The ICX_POR_ORACLE_ITEM_SUBTABLE is a pivotal yet often overlooked component in Oracle EBS procurement workflows. Its role in managing extended item attributes ensures flexibility for complex procurement scenarios, particularly in catalog-based requisitioning. Understanding its structure and relationships is essential for troubleshooting, reporting, or customizing iProcurement processes in EBS 12.1.1 and 12.2.2.
