Search Results po_headers_archive_all

The PO_HEADERS_ARCHIVE_ALL table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 serves as a critical repository for archived purchase order (PO) header data. This table is part of the Purchasing module and is designed to store historical PO header information that has been purged from the primary PO_HEADERS_ALL table, typically during data archival or cleanup processes. Below is a detailed examination of its structure, purpose, and integration within Oracle EBS.

Purpose and Functionality

The PO_HEADERS_ARCHIVE_ALL table acts as a safeguard for compliance, auditing, and reporting requirements by retaining historical PO header records. When POs are purged from the active PO_HEADERS_ALL table—either manually or via automated archival scripts—their header data is transferred to this archive table. This ensures that organizations can meet regulatory retention policies while maintaining database performance by reducing the volume of active transactional data.

Key Columns and Structure

The table mirrors the structure of PO_HEADERS_ALL but may include additional metadata like archival timestamps. Key columns include:

• PO_HEADER_ID: Unique identifier for the PO header.
• AGENT_ID: Buyer responsible for the PO.
• TYPE_LOOKUP_CODE: PO type (e.g., Standard, Blanket).
• SEGMENT1: PO number visible to users.
• VENDOR_ID: Supplier associated with the PO.
• CREATION_DATE: Original PO creation date.
• ARCHIVE_DATE: Timestamp when the record was archived.

Other columns capture approval statuses, currency, payment terms, and sourcing details, ensuring comprehensive historical tracking.

Integration with Oracle EBS Modules

The table integrates with several EBS modules:

• Purchasing: Links to archived lines (PO_LINES_ARCHIVE_ALL) and distributions (PO_DISTRIBUTIONS_ARCHIVE_ALL).
• Payables: References archived POs for invoice matching.
• General Ledger: Supports financial reporting by retaining cost distribution data.

Cross-references to PO_HEADERS_ALL and related archive tables ensure data integrity during archival and retrieval.

Data Archival Process

Archival is typically triggered by:

1. Manual Purge: Using Oracle's Purge utility or custom scripts.
2. Automated Jobs: Scheduled concurrent programs like "Purge Documents."

During archival, records are validated for dependencies (e.g., unpaid invoices) before migration to PO_HEADERS_ARCHIVE_ALL. The process may also archive related entities (lines, shipments) to maintain referential integrity.

Reporting and Compliance

The table enables:

• Audit Trails: Tracking PO lifecycle changes post-archival.
• Historical Analysis: Trend reporting on supplier performance or spending.
• Legal Compliance: Adherence to data retention laws (e.g., SOX, GDPR).

Custom reports can join this table with other archive tables or active data for comprehensive insights.

Technical Considerations

• Indexing: Proper indexing on PO_HEADER_ID, SEGMENT1, and ARCHIVE_DATE is critical for performance.
• Partitioning: Large volumes may necessitate partitioning by date ranges.
• Access Controls: Restricted via Oracle's data security mechanisms (e.g., VPD).

Conclusion

The PO_HEADERS_ARCHIVE_ALL table is a cornerstone of Oracle EBS's data retention strategy for procurement. By preserving historical PO headers, it balances operational efficiency with compliance needs, ensuring seamless integration across financial and supply chain modules. Proper configuration and maintenance of this table are essential for organizations leveraging Oracle EBS 12.1.1 or 12.2.2.
