The ONT.OE_UPGRADE_WSH_IFACE table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 serves as a critical interface table within the Order Management (OM) and Shipping Execution modules. It facilitates data migration and integration during system upgrades, particularly when transitioning from legacy shipping systems to the newer Shipping Execution module. This table acts as a staging area for shipping-related data before it is processed and transferred to the target tables in the Oracle Shipping module.

Purpose and Functionality

The primary purpose of ONT.OE_UPGRADE_WSH_IFACE is to ensure seamless data migration during upgrades, especially when moving from older versions of Oracle OM to versions 12.1.1 or 12.2.2. It captures shipping-related attributes such as delivery details, carrier information, freight terms, and shipping methods from legacy systems. The table is populated during the upgrade process, and its data is subsequently processed by concurrent programs or APIs to update the corresponding records in the WSH_DELIVERIES, WSH_DELIVERY_DETAILS, and other related shipping tables.

Key Columns and Structure

The table typically includes columns such as:
  • SHIPMENT_HEADER_ID: Unique identifier for the shipment header.
  • DELIVERY_ID: References the delivery record in the Shipping module.
  • SOURCE_LINE_ID: Links to the original order line in OM.
  • CARRIER_ID: Identifies the shipping carrier.
  • SHIP_METHOD_CODE: Specifies the shipping method (e.g., "GROUND," "AIR").
  • STATUS_FLAG: Indicates the processing status (e.g., 'P' for Pending, 'E' for Error).
  • ERROR_MESSAGE: Stores validation errors encountered during processing.

Integration with Upgrade Processes

During an upgrade, data from legacy shipping tables is extracted and loaded into ONT.OE_UPGRADE_WSH_IFACE. The Oracle Upgrade Assistant or custom scripts then invoke concurrent programs like "Interface Delivery Records" to validate and transfer this data to the Shipping Execution module. The STATUS_FLAG column is critical for tracking the success or failure of each record, allowing administrators to troubleshoot issues before finalizing the upgrade.

Common Challenges and Best Practices

  • Data Validation: Ensure legacy data aligns with the target schema to avoid errors.
  • Performance: Large datasets may require batch processing to avoid system bottlenecks.
  • Error Handling: Monitor the ERROR_MESSAGE column and resolve discrepancies promptly.

Conclusion

The ONT.OE_UPGRADE_WSH_IFACE table is a pivotal component in Oracle EBS upgrades, enabling the smooth transition of shipping data between modules. Proper configuration and validation during its use are essential to ensure data integrity and a successful upgrade process.
