The HZ_ADDRESS_USAGES table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical component of the Trading Community Architecture (TCA) module, which serves as the central repository for managing customer, supplier, and partner data. This table plays a pivotal role in defining how addresses are utilized across various business entities and processes within the Oracle EBS ecosystem. Below is a detailed summary of its structure, purpose, and functional significance.

Purpose and Context

The HZ_ADDRESS_USAGES table stores metadata that associates addresses (LOCATION_ID) with specific business entities (e.g., parties, sites, or accounts) and defines their usage contexts. It acts as a bridge between physical addresses (stored in HZ_LOCATIONS) and their functional applications (e.g., billing, shipping, or legal purposes). This enables organizations to maintain a single address record while reusing it across multiple entities with distinct purposes, ensuring data consistency and reducing redundancy.

Key Columns and Relationships

The table's structure includes the following critical columns:
  • ADDRESS_USAGE_ID: Primary key, uniquely identifying each address-usage association.
  • LOCATION_ID: Foreign key linking to HZ_LOCATIONS, referencing the physical address.
  • USAGE_CODE: Defines the purpose of the address (e.g., BILL_TO, SHIP_TO, HOME).
  • OWNER_TABLE_NAME and OWNER_TABLE_ID: Identify the entity (e.g., HZ_PARTY_SITES, HZ_CUST_ACCT_SITES) using the address.
  • PRIMARY_FLAG: Indicates whether the address is the primary one for its usage type.
  • STATUS: Tracks active/inactive status of the association.
The table integrates with other TCA entities like HZ_PARTIES, HZ_PARTY_SITES, and HZ_CUST_ACCT_SITES_ALL to support end-to-end address management.

Functional Significance

  1. Address Reusability: Enables a single address to serve multiple purposes (e.g., a customer site can be both a SHIP_TO and BILL_TO location).
  2. Hierarchical Management: Supports address inheritance across party hierarchies (e.g., a parent organization's legal address can propagate to subsidiaries).
  3. Process-Specific Routing: Drives workflows in Order Management, Accounts Receivable, and Procurement by tagging addresses with context-aware usage codes.
  4. Data Integrity: Ensures referential integrity through foreign key constraints with HZ_LOCATIONS and owner tables.

Integration with Oracle EBS Modules

The table is leveraged by:
  • Order Management (OM): Identifies shipping/billing addresses for sales orders.
  • Accounts Receivable (AR): Determines invoice delivery addresses.
  • Procurement: Maps supplier addresses for purchase orders.
  • Customer Relationship Management (CRM): Tracks service locations.

Customization and Extensions

Organizations can extend functionality by:
  • Adding custom USAGE_CODE values via lookups.
  • Creating triggers or APIs to enforce business rules (e.g., validating primary address uniqueness).
  • Integrating with geographic information systems (GIS) via LOCATION_ID.

Conclusion

The HZ_ADDRESS_USAGES table is a foundational element of Oracle EBS's address management framework, enabling flexible, reusable, and context-aware address associations. Its design aligns with TCA's goal of maintaining a single source of truth for entity data while supporting complex business processes across financial, supply chain, and CRM modules. Proper utilization of this table ensures operational efficiency, regulatory compliance, and enhanced data governance in multi-entity environments.
