The Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 versions utilize a structured set of tables and views to manage Bill of Materials (BOM) data, which is critical for manufacturing, engineering, and supply chain operations. The **DeepseekTRM - BOM Tables and Views** documentation provides a comprehensive reference for these database objects, detailing their relationships, key columns, and functional roles within the Oracle BOM module. Below is a detailed summary of the key tables and views in Oracle BOM, their purposes, and their interdependencies.

Core BOM Tables

The BOM module in Oracle EBS relies on foundational tables that store hierarchical and component-level data for assemblies, items, and routing structures. Key tables include:

  • BOM_BILL_OF_MATERIALS: Stores header-level BOM information, including assembly item IDs, alternate BOM designators, and effectivity dates. This table acts as the parent record for BOM structures.
  • BOM_INVENTORY_COMPONENTS: Contains component-level details such as item IDs, quantities, operation sequences, and supply types. It links to BOM_BILL_OF_MATERIALS via BILL_SEQUENCE_ID.
  • BOM_REFERENCE_DESIGNATORS: Tracks reference designators for components, often used in electronics manufacturing to map components to PCB locations.
  • BOM_SUB_COMPONENTS: Manages substitute components, allowing alternative items to be defined for primary components in a BOM.
  • BOM_ROUTINGS and BOM_OPERATION_SEQUENCES: Store routing and operation details for manufacturing processes, linking to BOM structures via ROUTING_SEQUENCE_ID.

Supporting Tables

Additional tables enhance BOM functionality by managing revisions, effectivity, and item attributes:

  • MTL_SYSTEM_ITEMS_B: The master item table, which stores item definitions referenced by BOM structures. Key columns include INVENTORY_ITEM_ID and ORGANIZATION_ID.
  • BOM_REVISIONS_B: Tracks revision details for BOMs and items, ensuring version control and auditability.
  • BOM_EFFECTIVITY_DATES: Manages date-effectivity rules for BOM components, enabling time-phased changes.

Key BOM Views

Oracle EBS provides views that simplify querying BOM data by joining underlying tables. Notable views include:

  • BOM_BILL_OF_MTLS_V: A comprehensive view combining BOM_BILL_OF_MATERIALS with item descriptions and revision data.
  • BOM_COMPONENTS_V: Aggregates component details from BOM_INVENTORY_COMPONENTS, MTL_SYSTEM_ITEMS_B, and reference designators.
  • BOM_EXPLOSIONS_V: Supports multi-level BOM explosions, displaying hierarchical relationships between parent and child items.

Integration with Other Modules

BOM tables integrate with Oracle Inventory, Work in Process (WIP), and Costing modules. For example:

  • WIP_ROUTING_OPERATIONS links to BOM_OPERATION_SEQUENCES for shop floor execution.
  • CST_ITEM_COSTS uses BOM data to calculate item costs based on component structures.

Conclusion

The **DeepseekTRM - BOM Tables and Views** documentation serves as a vital resource for Oracle EBS functional and technical teams. By detailing the schema architecture, key relationships, and usage scenarios, it enables efficient customization, reporting, and troubleshooting of BOM-related processes. Understanding these tables and views is essential for implementing accurate BOM structures, managing revisions, and ensuring seamless integration with manufacturing and costing modules in Oracle EBS 12.1.1 and 12.2.2.
