The OP_PRCE_MST table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical data structure within the Order Management (OM) module, specifically related to pricing functionality. This table serves as the master repository for price lists, which are fundamental to the pricing engine in Oracle Order Management and Oracle Advanced Pricing. Below is a detailed breakdown of its structure, purpose, and integration within Oracle EBS.

Purpose and Functionality

The OP_PRCE_MST table stores header-level information for price lists, which define the pricing rules and adjustments applied to products or services sold to customers. Price lists are essential for determining the final selling price of items, incorporating discounts, surcharges, and other pricing modifiers. This table acts as the parent entity for related pricing details stored in subordinate tables like OP_PRCE_DTL (price list lines) and QP_PRICING_ATTRIBUTES.

Key Columns and Structure

The table includes several critical columns that define price list attributes:
  • PRICE_LIST_ID: Primary key identifier for the price list.
  • NAME: Descriptive name of the price list.
  • CURRENCY_CODE: Currency in which prices are defined.
  • START_DATE_ACTIVE and END_DATE_ACTIVE: Validity period of the price list.
  • DESCRIPTION: Additional details about the price list.
  • CREATED_BY, CREATION_DATE, LAST_UPDATED_BY, LAST_UPDATE_DATE: Audit columns tracking record creation and modifications.

Integration with Oracle EBS Modules

The OP_PRCE_MST table integrates with multiple Oracle EBS modules:
  • Order Management (OM): Price lists are referenced during order entry to calculate line prices.
  • Advanced Pricing (QP): Used to define complex pricing rules, modifiers, and eligibility criteria.
  • Inventory (INV): Links items to price lists for cost and selling price validation.
  • Receivables (AR): Influences invoicing by providing the base price for billed items.

Technical Considerations

  • Indexing: The PRICE_LIST_ID column is typically indexed for performance optimization in pricing queries.
  • Partitioning: In large implementations, this table may be partitioned by date ranges or organizational units.
  • API Usage: Direct DML operations on this table are discouraged; instead, Oracle provides APIs like QP_PRICE_LIST_PUB for safe modifications.

Customization and Extension

Organizations often extend the OP_PRCE_MST table by adding custom columns to support unique pricing requirements. Such extensions should be implemented via Oracle's standard extension methodologies (e.g., Descriptive Flexfields) to ensure upgrade compatibility.

Data Flow and Dependencies

Price lists flow downstream to:
  • Sales orders via the OE_ORDER_LINES_ALL table.
  • Invoices through the RA_CUSTOMER_TRX_LINES_ALL table.
  • Reporting systems via Oracle BI Publisher or other analytics tools.

Upgrade Implications

Between EBS 12.1.1 and 12.2.2, the OP_PRCE_MST table's structure remains largely consistent, but underlying pricing engine enhancements in 12.2.2 may affect how data is processed. Customizations should be reviewed during upgrades.

Conclusion

The OP_PRCE_MST table is a cornerstone of Oracle EBS pricing architecture, enabling flexible and scalable price management across sales and distribution processes. Proper understanding of its structure and relationships is essential for effective configuration, customization, and maintenance of Oracle Order Management and Advanced Pricing modules.
