The AR_LOCATION_RATES_OLD table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical data structure within the Accounts Receivable (AR) module. It serves as a historical repository for tax rate assignments associated with customer locations, enabling compliance with tax regulations and facilitating accurate tax calculations during invoice processing. This table is primarily utilized when tax rate updates occur, preserving previous rate configurations for audit trails and reporting purposes.

Table Structure and Key Columns

The AR_LOCATION_RATES_OLD table contains the following essential columns:

  • LOCATION_RATE_ID: Primary key identifier for the tax rate record.
  • LOCATION_ID: Foreign key linking to AR_LOCATIONS, identifying the customer site.
  • TAX_CODE: The tax jurisdiction code applied to the location.
  • RATE: The historical tax rate percentage stored for reference.
  • START_DATE and END_DATE: Defines the effective period of the tax rate.
  • CREATION_DATE, CREATED_BY, LAST_UPDATE_DATE, LAST_UPDATED_BY: Standard Oracle audit columns.

Functional Role in Tax Management

When tax rates are modified for a customer location via the AR Tax Rates form or APIs, Oracle EBS archives the superseded rates in AR_LOCATION_RATES_OLD. This ensures:

  • Historical Accuracy: Retains prior tax configurations for financial reporting and compliance.
  • Audit Compliance: Supports tax audits by providing a traceable record of rate changes.
  • Data Integrity: Prevents loss of critical tax data during updates.

Integration with Other Modules

The table interacts with:

  • AR_LOCATIONS: Contains customer address details linked via LOCATION_ID.
  • AR_TAX_CODES: Provides tax jurisdiction definitions referenced by TAX_CODE.
  • AR_TRANSACTION_HISTORY: May reference historical rates for invoice adjustments.

Technical Considerations

In EBS 12.1.1 and 12.2.2, the table is managed through:

  • Tax Rate Maintenance Forms: Manual updates trigger archival to AR_LOCATION_RATES_OLD.
  • APIs: Programmatic rate changes via AR_TAX_PUB package handle archival automatically.
  • Purge Mechanisms: Requires custom scripts to manage data growth, as Oracle does not provide standard purge programs for this table.

Customization and Extension Points

Common extensions include:

  • Triggers: Additional validation during rate changes.
  • Reports: Custom tax history reports querying this table.
  • Data Migrations: Mapping legacy tax rates during implementations.

Conclusion

The AR_LOCATION_RATES_OLD table is a vital component of Oracle EBS's tax infrastructure, ensuring regulatory compliance and data continuity. Its design supports complex tax scenarios while maintaining a clear audit trail. Administrators should monitor its growth and implement retention policies to balance storage needs with compliance requirements.
