The PO.PO_HEADERS_INTERFACE table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 serves as a critical staging area for importing purchase order (PO) header data into the system. This table is part of the Oracle Purchasing Open Interface, which facilitates the bulk loading of purchase orders from external systems or legacy applications into Oracle EBS. The interface architecture ensures data validation, transformation, and processing before records are transferred to the base tables (PO_HEADERS_ALL, PO_LINES_ALL, etc.). Below is a detailed analysis of its structure, functionality, and integration within Oracle EBS.

Purpose and Role

The PO_HEADERS_INTERFACE table acts as an intermediary repository where external systems can insert PO header records before they are validated and processed by the Import Purchase Orders concurrent program (POXPOIMP). This program reads the interface table, validates data against Oracle Purchasing rules, and creates or updates POs in the core transactional tables. The interface mechanism supports both new PO creation and modifications to existing POs.

Key Columns and Data Structure

The table contains columns that mirror the attributes of a purchase order header, including:
  • INTERFACE_HEADER_ID: Primary key, uniquely identifying each record in the interface table.
  • BATCH_ID: Groups multiple records for processing in a single batch.
  • PROCESS_CODE: Tracks the status of records (e.g., PENDING, PROCESSED, ERROR).
  • ACTION: Specifies the operation (INSERT, UPDATE, DELETE).
  • ORG_ID: Identifies the operating unit for multi-org environments.
  • PO_HEADER_ID: References an existing PO if the action is an update or delete.
  • VENDOR_ID, VENDOR_SITE_ID: Supplier and site details.
  • AGENT_ID: Buyer responsible for the PO.
  • CURRENCY_CODE, RATE_TYPE, RATE_DATE: Financial attributes.
  • APPROVED_FLAG, APPROVED_DATE: Approval status.

Integration and Processing Workflow

  1. Data Loading: External systems or scripts insert records into PO_HEADERS_INTERFACE, populating mandatory fields like ACTION, ORG_ID, and supplier details.
  2. Validation: The Import Purchase Orders program validates data against Oracle Purchasing rules (e.g., valid vendor, currency, buyer). Errors are logged in PO_INTERFACE_ERRORS.
  3. Processing: Valid records are transferred to PO_HEADERS_ALL, and related lines (from PO_LINES_INTERFACE) are processed.
  4. Status Update: The PROCESS_CODE is updated to PROCESSED or ERROR, and error messages are captured if applicable.

Customization and Best Practices

  • Error Handling: Query PO_INTERFACE_ERRORS to troubleshoot failures. Common issues include missing vendor data or invalid dates.
  • Performance: For large data volumes, use batch processing and index the BATCH_ID column.
  • Extensions: Custom columns can be added to the interface table but require modifications to the PL/SQL validation logic.
  • Concurrency: Avoid overlapping runs of the Import Purchase Orders program to prevent data corruption.

Conclusion

The PO.PO_HEADERS_INTERFACE table is a foundational component of Oracle EBS Purchasing Open Interface, enabling seamless integration of PO data from heterogeneous systems. Its design ensures data integrity through rigorous validation while providing flexibility for customization. Proper utilization of this interface streamlines procurement operations and enhances data accuracy in Oracle EBS deployments.
