The CM_CMPT_MTL table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical data structure within the Configurator module, specifically supporting the Oracle Configurator and Oracle Advanced Pricing functionalities. This table stores component material information, which is essential for defining and managing configurable products, bills of materials (BOMs), and pricing rules. Below is a detailed analysis of its purpose, structure, and integration within Oracle EBS.

Purpose and Functional Context

The CM_CMPT_MTL table serves as a repository for component-level material data, linking configurable items to their constituent parts. It plays a pivotal role in:
  • Product Configuration: Stores attributes and relationships between parent and child items in a configurable BOM.
  • Pricing Rules: Facilitates dynamic pricing by associating materials with pricing modifiers or surcharges.
  • Inventory and Order Management: Ensures accurate material requirements are propagated to downstream processes like order fulfillment and procurement.

Table Structure and Key Columns

The table's schema includes columns that define material relationships, configurations, and transactional attributes. Key columns include:
  • CMPT_MTL_ID: Primary key, uniquely identifying each component material record.
  • CONFIG_ITEM_ID: References the configurable item (from MTL_SYSTEM_ITEMS).
  • COMPONENT_ITEM_ID: Links to the child item in the BOM structure.
  • ORGANIZATION_ID: Specifies the inventory organization for the material.
  • START_DATE/END_DATE: Defines the validity period for the component association.
  • ATTRIBUTE_GROUP: Captures user-defined attributes for extensibility.

Integration with Oracle EBS Modules

CM_CMPT_MTL integrates with several core EBS modules:
  • Inventory (INV): Interfaces with MTL_SYSTEM_ITEMS for item master data.
  • Bills of Material (BOM): Works with BOM_COMPONENTS to enforce hierarchical BOM rules.
  • Order Management (OM): Ensures configured items are validated against material availability.
  • Advanced Pricing (QP): Supports price adjustments based on component selections.

Technical Considerations

  • Indexing: Typically indexed on CMPT_MTL_ID, CONFIG_ITEM_ID, and ORGANIZATION_ID for performance.
  • Partitioning: In high-volume environments, partitioning by ORGANIZATION_ID may be implemented.
  • API Usage: Modifications should use Oracle Configurator APIs (e.g., CZ_API) to maintain data integrity.

Customization and Extensions

The table supports extensibility via:
  • Descriptive Flexfields (DFFs): For capturing industry-specific attributes.
  • Triggers/Views: Custom logic can be added via database triggers or derived views.

Conclusion

The CM_CMPT_MTL table is a foundational element in Oracle EBS for managing configurable products. Its design ensures seamless integration across inventory, BOM, and pricing modules, while its extensibility supports complex business requirements. Proper understanding of this table is essential for implementing and maintaining Oracle Configurator solutions in EBS 12.1.1 or 12.2.2 environments.
