The BOM_BILL_OF_MATERIALS table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a fundamental data structure within the Bills of Material (BOM) module, serving as the primary repository for bill of material header information. This table stores metadata that defines the structure, attributes, and relationships of assemblies and components in a manufacturing or engineering environment. It plays a critical role in product lifecycle management, costing, and production planning. ### **Key Attributes of BOM_BILL_OF_MATERIALS** The table contains several key columns that define the characteristics of a bill of material: - **BILL_SEQUENCE_ID**: A unique identifier for each BOM record. - **ASSEMBLY_TYPE**: Specifies whether the BOM is for a standard assembly, model, option class, or planning item. - **ASSEMBLY_ITEM_ID**: References the inventory item (from MTL_SYSTEM_ITEMS_B) that represents the parent assembly. - **ORGANIZATION_ID**: Links to the inventory organization where the BOM is defined. - **ALTERNATE_BOM_DESIGNATOR**: Identifies alternate BOMs for the same assembly. - **COMMON_ASSEMBLY_ITEM_ID**: Used in common BOM structures across organizations. - **EFFECTIVITY_DATE**: The date from which the BOM becomes active. - **IMPLEMENTATION_DATE**: The date when the BOM was implemented. - **DISABLE_DATE**: The date when the BOM is no longer active. - **SPECIFIC_ASSEMBLY_COMMENT**: Optional remarks about the BOM. ### **Functional Role in Oracle EBS** The BOM_BILL_OF_MATERIALS table works in conjunction with other key tables such as: - BOM_INVENTORY_COMPONENTS (stores component items and their quantities). - BOM_REFERENCE_DESIGNATORS (tracks component placements on PCBs or assemblies). - BOM_SUBSTITUTE_COMPONENTS (manages substitute parts). This table supports various business processes, including: 1. **Engineering and Manufacturing BOMs**: Defines product structures for production and engineering changes. 2. **Cost Roll-Up**: Facilitates cost calculations by establishing parent-child relationships. 3. **Configurable Products**: Enables model and option class BOMs for configure-to-order scenarios. 4. **Multi-Organization BOM Sharing**: Allows common BOMs across different inventory organizations. ### **Integration with Other Modules** The BOM_BILL_OF_MATERIALS table integrates with: - **Inventory (INV)**: Validates assembly and component items. - **Work in Process (WIP)**: Provides BOM data for manufacturing orders. - **Cost Management (CST)**: Supports cost roll-up and variance analysis. - **Order Management (OM)**: Facilitates configurable item pricing and fulfillment. ### **Technical Considerations** - **Indexing**: Key columns like BILL_SEQUENCE_ID, ASSEMBLY_ITEM_ID, and ORGANIZATION_ID are indexed for performance. - **Data Integrity**: Foreign key constraints ensure valid references to items and organizations. - **API Access**: Oracle provides APIs (BOM_BO_PUB) for programmatic BOM creation/modification. ### **Conclusion** The BOM_BILL_OF_MATERIALS table is a cornerstone of Oracle EBS’s BOM module, enabling structured product definitions, cost management, and seamless integration with manufacturing and supply chain processes. Proper utilization of this table ensures accurate product configurations, efficient production planning, and streamlined engineering change management.
