The QP_DEBUG_REQ_LINES table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical debugging table used by the Oracle Pricing (QP) module to log and analyze pricing request line details during the execution of complex pricing calculations. This table captures granular transaction-level data, enabling administrators and developers to diagnose issues related to price determination, modifier applications, and qualification rules. Below is a detailed technical breakdown of its structure, purpose, and usage within Oracle EBS.

Purpose and Context

The Oracle Pricing module processes pricing requests from various EBS applications, such as Order Management (OM), Quoting, and Procurement. The QP_DEBUG_REQ_LINES table acts as a diagnostic repository, storing intermediate results and metadata for each line item processed during pricing engine execution. It is particularly useful for troubleshooting scenarios where prices, discounts, or surcharges deviate from expectations, or when complex pricing rules (e.g., matrix pricing, tiered discounts) fail to apply correctly.

Table Structure

The table typically includes the following key columns:
  • REQUEST_LINE_ID: Primary key identifier for each debug entry.
  • REQUEST_HEADER_ID: References the parent pricing request header in QP_DEBUG_REQ_HEADERS.
  • LINE_INDEX: Sequential index of the line within the request.
  • PRICING_PHASE: Phase of pricing execution (e.g., "Qualification," "Price Calculation," "Adjustment").
  • ITEM_ID: Identifier of the item being priced.
  • PRICE_LIST_ID: Reference to the price list used.
  • CALCULATED_PRICE: Interim or final computed price.
  • APPLIED_MODIFIERS: List of modifiers (discounts/surcharges) applied to the line.
  • ERROR_MESSAGE: Captures errors encountered during processing.
  • CREATION_DATE: Timestamp of record creation.

Functional Workflow

When a pricing request is initiated (e.g., via an OM sales order), the QP engine populates QP_DEBUG_REQ_LINES with line-level details at each processing stage:
  1. Initialization: Line item attributes (product, quantity, UOM) are logged.
  2. Qualification: Rules determining eligibility for price lists/modifiers are recorded.
  3. Calculation: Base price and adjusted prices are captured with breakdowns.
  4. Post-Processing: Final prices, tax implications, and errors (if any) are stored.

Debugging Use Cases

Administrators leverage this table to:
  • Verify why specific modifiers were/were not applied.
  • Audit price derivation logic for compliance.
  • Identify performance bottlenecks in complex pricing scenarios.
  • Correlate errors with specific line items during support escalations.

Technical Considerations

In EBS 12.2.2, the table may integrate with Oracle's Online Patching (ADOP) framework, ensuring debug data remains consistent during patching cycles. For performance optimization, purging old records via concurrent programs (e.g., "QP: Purge Debug Tables") is recommended. The table's data is often queried alongside QP_DEBUG_REQ_HEADERS and QP_DEBUG_ATTRS for end-to-end analysis.

Conclusion

The QP_DEBUG_REQ_LINES table is an indispensable tool for maintaining pricing accuracy and transparency in Oracle EBS. Its structured logging capability provides visibility into the pricing engine's decision-making process, facilitating rapid issue resolution and ensuring alignment with business pricing policies. Proper utilization of this table can significantly reduce debugging time for pricing-related discrepancies in high-volume transactional environments.
