The OE_CONC_REQUEST_IFACE table in Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 serves as a critical interface table for managing concurrent program requests related to Order Management (OM) module operations. This table acts as a staging area where data is temporarily stored before being processed by concurrent programs, ensuring seamless integration between external systems and Oracle OM workflows. Below is a detailed technical breakdown of its structure, purpose, and usage.

Purpose and Functional Overview

The primary function of OE_CONC_REQUEST_IFACE is to facilitate asynchronous processing of Order Management tasks, such as order import, workflow background processing, and bulk data operations. It enables external systems or batch processes to submit requests without requiring real-time interaction with the OM module. Key use cases include:
  • Order Import: Staging order data from external systems (e.g., EDI, web stores) before validation and import into OM tables.
  • Bulk Processing: Handling high-volume updates (e.g., price adjustments, status changes) via concurrent programs.
  • Error Handling: Capturing failed transactions for reprocessing or analysis.

Table Structure and Key Columns

The table's schema includes columns to track request metadata, payload data, and processing status. Notable columns include:
  • REQUEST_ID: Primary key, referencing FND_CONCURRENT_REQUESTS for concurrent program tracking.
  • BATCH_ID: Groups related requests (e.g., multiple orders in a single import batch).
  • PROCESS_STATUS: Indicates state (e.g., 'PENDING', 'PROCESSED', 'ERROR').
  • TRANSACTION_TYPE: Specifies the operation (e.g., 'ORDER_IMPORT', 'UPDATE_STATUS').
  • PAYLOAD_DATA: Typically stores XML or delimited data for the transaction.
  • CREATION_DATE/LAST_UPDATE_DATE: Timestamps for auditing.

Integration with Oracle EBS Components

OE_CONC_REQUEST_IFACE interacts with several EBS components:
  1. Concurrent Manager: Processes records via programs registered in FND_CONCURRENT_PROGRAMS.
  2. Order Management APIs: Validates and transforms interface data into OM entities (e.g., OE_ORDER_HEADERS_ALL).
  3. Workflow Engine: Triggers OM workflows (e.g., order booking) post-processing.

Processing Flow

A typical data flow involves:
  1. Data Insertion: External systems or PL/SQL scripts populate the table with PROCESS_STATUS = 'PENDING'.
  2. Concurrent Program Execution: A seeded or custom program (e.g., "Order Import") processes pending records.
  3. Validation & Transformation: Data is validated against OM rules and written to base tables.
  4. Status Update: Successful records are marked 'PROCESSED'; errors are flagged with error messages.

Customization Considerations

While Oracle provides seeded programs, extensions often require:
  • Custom Concurrent Programs: To handle unique transaction types or data formats.
  • Error Handling Routines: To log failures to OE_INTERFACE_ERRORS or notify stakeholders.
  • Performance Tuning: Indexing BATCH_ID or partitioning for high-volume interfaces.

Version-Specific Notes

Differences between 12.1.1 and 12.2.2 are minimal, but 12.2.2 may include:
  • Enhanced XML payload support for cloud integrations.
  • Tighter integration with Oracle Integration Cloud (OIC) in later patches.

Conclusion

OE_CONC_REQUEST_IFACE is a pivotal component in Oracle EBS Order Management, enabling scalable, asynchronous processing of order-related operations. Proper implementation ensures robust data integration while maintaining system performance and auditability. Developers should adhere to Oracle's interface standards and leverage seeded APIs to minimize custom code maintenance.
