The OE_ORDER_HEADER_HISTORY table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical repository for historical data related to order headers in the Order Management (OM) module. This table stores snapshots of changes made to order header records in the OE_ORDER_HEADERS_ALL table, enabling audit trails, compliance reporting, and historical analysis. Below is a detailed breakdown of its structure, functionality, and integration within Oracle EBS.

Purpose and Functionality

The OE_ORDER_HEADER_HISTORY table captures historical versions of order header records whenever modifications occur. This includes changes to attributes such as order status, pricing, customer details, or shipping information. The table serves as a log for tracking order evolution over time, supporting regulatory requirements (e.g., SOX compliance) and business process analysis. Unlike transactional tables, it retains immutable records, ensuring data integrity for historical reporting.

Key Columns and Structure

The table's schema includes columns that mirror OE_ORDER_HEADERS_ALL, along with metadata for historical tracking:
  • HEADER_ID: Foreign key linking to the original order header.
  • VERSION_NUMBER: Incremental version identifier for each change.
  • CREATION_DATE/LAST_UPDATE_DATE: Timestamps for record creation/modification.
  • CREATED_BY/LAST_UPDATED_BY: User IDs responsible for changes.
  • CHANGE_REASON: Optional field documenting the reason for modifications.
  • STATUS, CUSTOMER_ID, PRICE_LIST_ID: Snapshot of order attributes at the time of change.

Integration with Oracle EBS Modules

The table interacts with several EBS components:
  1. Order Management (OM): Primary source of order header changes, triggering history records via APIs or workflows.
  2. Inventory (INV): Updates to shipping or fulfillment data may propagate to history.
  3. Receivables (AR): Links to invoicing and customer data changes.
  4. Advanced Pricing: Captures historical pricing adjustments.

Technical Considerations

  • Partitioning: In high-volume environments, partitioning by CREATION_DATE improves query performance.
  • Indexing: Common indexes include HEADER_ID and VERSION_NUMBER for retrieval efficiency.
  • Purge Policies: Oracle provides archival utilities (e.g., FND_PURGE) to manage data growth.

Customization and Extensions

Organizations may extend functionality by:
  • Adding custom columns via AD_ZD patches for additional tracking.
  • Creating triggers to capture non-standard attributes.
  • Integrating with BI tools (e.g., Oracle BI Publisher) for historical trend analysis.

Performance Implications

Frequent writes to this table can impact system performance. Recommendations include:
  • Limiting history retention to required periods.
  • Scheduling batch operations during off-peak hours.
  • Monitoring table growth via DBA_SEGMENTS.

Conclusion

The OE_ORDER_HEADER_HISTORY table is a foundational element for auditability and historical reporting in Oracle EBS Order Management. Its design ensures traceability of order lifecycle changes while integrating seamlessly with core EBS modules. Proper configuration and maintenance are essential to balance compliance needs with system performance.
