The IGI_DUN_TEMP table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a temporary table utilized within the context of the iGATE (Internet Global Architecture for Treasury and Enterprise Management) module, specifically for Dunning (Collections Management) processes. Dunning refers to the systematic approach of tracking and managing overdue customer payments, ensuring timely collections while maintaining compliance with organizational policies. This table serves as a staging area for temporary data storage during dunning-related batch processes, such as generating dunning letters, calculating penalties, or updating customer account statuses.

Key Attributes and Structure

The IGI_DUN_TEMP table typically contains fields that facilitate intermediate processing of dunning-related data. While the exact schema may vary based on customizations, common columns include:
  • TRANSACTION_ID: A unique identifier for each dunning transaction.
  • CUSTOMER_ID: References the customer account in RA_CUSTOMERS.
  • INVOICE_NUMBER: Links to the original invoice in RA_CUSTOMER_TRX.
  • DUE_DATE: The payment due date of the invoice.
  • OVERDUE_DAYS: Calculated field indicating days past the due date.
  • DUNNING_LEVEL: Tracks the escalation stage (e.g., 1st reminder, 2nd reminder).
  • PENALTY_AMOUNT: Stores computed late payment penalties.
  • STATUS_FLAG: Indicates processing status (e.g., 'P' for Pending, 'C' for Complete).
  • CREATION_DATE and LAST_UPDATE_DATE: Audit columns for tracking record lifecycle.

Functional Role in Oracle EBS

The table is primarily used in the following scenarios:
  1. Batch Dunning Letter Generation: During periodic dunning runs, overdue invoices are extracted into IGI_DUN_TEMP, where they are sorted by customer, overdue duration, and other criteria before generating dunning communications.
  2. Penalty Calculation: Interim penalty amounts are computed and stored here before being posted to the general ledger via IGI_DUN_JOURNALS or similar interfaces.
  3. Workflow Integration: Serves as a buffer for approvals in workflows where dunning actions require managerial review.
  4. Reporting and Analytics: Provides a snapshot of pending dunning activities for real-time dashboards or reconciliation reports.

Technical Considerations

  • Performance: As a temporary table, IGI_DUN_TEMP is optimized for high-volume inserts/deletes during batch jobs. Indexes on CUSTOMER_ID and STATUS_FLAG are common to improve query performance.
  • Purge Mechanisms: Automated jobs (e.g., Concurrent Programs) typically truncate the table post-processing to free space, as data is transient by design.
  • Integration Points: Interfaces with core EBS modules like Receivables (AR), General Ledger (GL), and Customer Data Hub (HZ) via APIs or direct SQL.

Customization and Extensions

In implementations where standard dunning logic is extended, IGI_DUN_TEMP may include additional columns such as:
  • DISPUTE_REASON_CODE: To categorize customer disputes during dunning.
  • LEGAL_HOLD_FLAG: For integrations with legal hold management systems.
  • CUSTOM_ATTRIBUTE1-15: Flexfields for organization-specific data capture.

Conclusion

The IGI_DUN_TEMP table is a critical component in Oracle EBS's dunning architecture, acting as a transient repository that ensures efficient processing of collections workflows. Its design balances flexibility for custom business rules with performance requirements for high-volume transaction environments. Administrators should monitor its usage patterns and purge cycles to maintain optimal system performance, especially in large-scale deployments with frequent dunning cycles.
