The OKE_K_HEADERS_H table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical repository for storing historical data related to contract headers in the Oracle Contracts for the Public Sector (OKE) module. This table is part of the Oracle Contracts Core schema and serves as an audit trail for changes made to contract headers, ensuring compliance, traceability, and historical reporting. Below is a detailed analysis of its structure, purpose, and integration within Oracle EBS.

Purpose and Functionality

The OKE_K_HEADERS_H table captures historical snapshots of contract header records from the primary table, OKE_K_HEADERS. It is designed to retain all modifications made to contract headers, including updates to key attributes such as contract numbers, descriptions, statuses, dates, and associated parties. This historical tracking is essential for auditing, regulatory compliance, and dispute resolution in public sector contracting.

Key Columns and Structure

The table includes columns such as:

  • K_HEADER_ID: The primary key linking to OKE_K_HEADERS.
  • START_DATE_ACTIVE and END_DATE_ACTIVE: Define the validity period of the historical record.
  • CREATED_BY, CREATION_DATE, LAST_UPDATED_BY, and LAST_UPDATE_DATE: Track authorship and timestamps of changes.
  • CONTRACT_NUMBER, DESCRIPTION, STATUS_CODE: Core contract attributes.
  • PARTY_ID and PARTY_SITE_ID: References to involved parties and locations.
These columns ensure comprehensive historical data retention while maintaining relational integrity with other OKE tables like OKE_K_LINES and OKE_K_PARTIES.

Integration with Oracle EBS Modules

OKE_K_HEADERS_H integrates with:

  • Oracle Projects: For contract-funded project tracking.
  • Oracle Financials: To align contract terms with invoicing and payment schedules.
  • Oracle Procurement: For linking contracts to purchase agreements.
This cross-module integration ensures seamless data flow and reporting across procurement, execution, and financial closeout phases.

Technical Considerations

In EBS 12.1.1 and 12.2.2, the table is optimized for:

  • Performance: Indexes on K_HEADER_ID and date columns facilitate efficient querying.
  • Data Retention: Policies may be implemented to archive older records, balancing storage and compliance needs.
  • Security: Access is restricted via Oracle's data security model (VPD, roles).

Conclusion

The OKE_K_HEADERS_H table is a foundational component of Oracle Contracts for the Public Sector, providing robust historical tracking for contract headers. Its design supports compliance, auditability, and integration with core EBS modules, making it indispensable for public sector entities leveraging Oracle EBS 12.1.1 or 12.2.2.
