The POA.EDW_DUNS_NUMBER_LTC table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical data entity that typically stores Dun & Bradstreet (DUNS) number-related information for long-term customer (LTC) records. DUNS numbers are unique nine-digit identifiers assigned to business entities by Dun & Bradstreet, widely used for credit reporting, supplier onboarding, and compliance tracking in enterprise systems. This table is often part of a larger data warehouse or operational reporting schema (POA schema in this case) and serves as a reference for integrating third-party business data with Oracle EBS modules such as Accounts Receivable (AR), Supplier Lifecycle Management (SLM), or Customer Data Management (CDH).

Table Structure and Key Fields

The POA.EDW_DUNS_NUMBER_LTC table likely contains the following key columns:
  • DUNS_NUMBER: The primary key storing the nine-digit DUNS identifier.
  • CUSTOMER_ID: Foreign key linking to RA_CUSTOMERS or HZ_PARTIES in Oracle EBS.
  • LEGAL_ENTITY_CODE: Associates the DUNS number with a legal entity in XLE_ENTITY_PROFILES.
  • VALIDATION_STATUS: Indicates DUNS verification status (e.g., 'Verified', 'Pending').
  • EFFECTIVE_START_DATE and EFFECTIVE_END_DATE: Temporal attributes for historical tracking.
  • LAST_UPDATE_DATE and CREATED_BY: Standard Oracle EBS audit columns.

Integration with Oracle EBS Modules

In EBS 12.1.1/12.2.2, this table supports:
  1. Supplier Management: Integrates with PO_VENDORS for supplier validation during onboarding.
  2. Customer Hierarchy: Links to HZ_CUST_ACCOUNTS to map corporate family structures using DUNS hierarchies.
  3. Compliance Reporting: Used in OFAC/SOX reports via Oracle Financial Services Analytical Applications (OFSAA).
  4. Data Quality: Synchronizes with Oracle Data Quality for DUNS validation workflows.

Technical Implementation

The table is typically populated via:
  • Batch processes using Oracle Integration Broker or SOA composites.
  • Real-time APIs from Dun & Bradstreet's Global Data Integration (GDI) platform.
  • ETL jobs in Oracle Data Integrator (ODI) when part of an EDW layer.

Customizations and Extensions

Common enhancements include:
  • Adding custom fields like GEOGRAPHY_CODE for regional compliance.
  • Creating triggers to enforce DUNS validation rules against FND_LOOKUP_VALUES.
  • Building Materialized Views for performance optimization in global deployments.

Security Considerations

Access is typically controlled via:
  • Oracle Role-Based Access Control (RBAC) tied to FND_RESPONSIBILITIES.
  • VPD (Virtual Private Database) policies for multi-org access control.
  • Data masking in clones per Oracle Advanced Security.

Migration and Upgrade Impacts

Between EBS 12.1.1 and 12.2.2:
  • Online Patching (ADOP) requires testing for EDW table dependencies.
  • JSON-based REST APIs in 12.2.2 may replace legacy integration methods.
  • In-Memory Column Store (IMCS) in 12.2.2 can accelerate analytical queries.
This table exemplifies Oracle EBS's extensibility in integrating third-party reference data while maintaining compliance with global business standards.
