Search Results bom_operation_sequences




The BOM_OPERATION_SEQUENCES table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical component of the Bills of Material (BOM) module, serving as the repository for manufacturing operation sequences within a routing. It defines the order of operations required to manufacture an item, linking them to specific departments, resources, and tools. This table plays a pivotal role in production planning, costing, and scheduling by providing the structural framework for manufacturing processes.

Key Attributes of BOM_OPERATION_SEQUENCES

  • OPERATION_SEQUENCE_ID: Primary key, uniquely identifying each operation sequence.
  • ASSEMBLY_ITEM_ID: References the inventory item (from MTL_SYSTEM_ITEMS_B) being manufactured.
  • ORGANIZATION_ID: Specifies the inventory organization where the operation is performed.
  • ROUTING_SEQUENCE_ID: Links to the parent routing (BOM_OPERATIONAL_ROUTINGS).
  • OPERATION_SEQ_NUM: Defines the execution order of operations within a routing.
  • STANDARD_OPERATION_ID: References a predefined operation (BOM_STANDARD_OPERATIONS).
  • DEPARTMENT_ID: Associates the operation with a manufacturing department (HR_ALL_ORGANIZATION_UNITS).
  • MINIMUM_TRANSFER_QUANTITY: Specifies batch size constraints for production flow.

Functional Significance

The table enables:
  1. Routing Definition: Establishes the sequence of operations (e.g., cutting, welding, assembly) with attributes like lead time and yield.
  2. Resource Allocation: Through child table BOM_OPERATION_RESOURCES, it assigns machines, labor, and tools to each operation.
  3. Cost Rollup: Operation costs (from BOM_OPERATION_CODES) aggregate into item costs via this structure.
  4. Shop Floor Control: Provides the execution blueprint for Work in Process (WIP) modules.

Integration Points

Related Module Integration Purpose
Work in Process (WIP) Converts routing data into discrete jobs or repetitive schedules
Cost Management Sources operation-based costs for item cost calculations
Capacity Planning Provides operation duration data for resource loading

Technical Considerations

  • Indexes: Key indexes include BOM_OPERATION_SEQUENCES_U1 (PK), BOM_OPERATION_SEQUENCES_N1 (ASSEMBLY_ITEM_ID), and BOM_OPERATION_SEQUENCES_N2 (ROUTING_SEQUENCE_ID).
  • API Access: Recommended to use BOM_ROUTING_PUB package for data manipulation to maintain integrity.
  • Audit Columns: Includes CREATION_DATE, LAST_UPDATE_DATE, and CREATED_BY for compliance tracking.

Version-Specific Notes

In 12.2.2, enhancements include:
  • Extended support for parallel operations through OPERATION_TYPE field
  • Integration with Oracle Manufacturing Cloud through web services
  • Improved validations against BOM_PARAMETERS controls
This table's proper configuration is essential for accurate manufacturing execution, with its data flowing downstream to shop floor documentation, quality plans, and ERP-driven automation systems. Understanding its structure is crucial for implementing lean manufacturing practices and Industry 4.0 initiatives within Oracle EBS environments.
