Overview

The BOM_OPERATION_RESOURCES table is a core transactional entity within the Oracle E-Business Suite Bills of Material (BOM) module. It serves as the definitive repository for defining and storing the specific resources required to perform a manufacturing operation within a routing. Each record in this table links a resource—such as a machine, labor type, or tool—to an operation sequence, detailing the quantity, usage, and scheduling basis for that resource. Its primary role is to establish the detailed cost and capacity planning foundation for production processes, enabling accurate product costing, shop floor scheduling, and resource requirement planning.

Key Information Stored

The table's structure captures the relationship between operations and their constituent resources. Its primary key is a composite of OPERATION_SEQUENCE_ID, which links to the parent operation in BOM_OPERATION_SEQUENCES, and RESOURCE_SEQ_NUM, which uniquely identifies the resource within that operation. Critical columns include RESOURCE_ID, which identifies the resource master definition; USAGE_RATE_OR_AMOUNT, which specifies the quantity of the resource consumed per operation; BASIS_TYPE, indicating if the resource usage is based on 'Item' or 'Lot'; and ACTIVITY_ID, which optionally links the resource to a cost activity in the CST_ACTIVITIES table for detailed cost accumulation. Additional columns manage scheduling, such as SCHEDULE_FLAG and ASSIGNED_UNITS.

Common Use Cases and Queries

This table is central to manufacturing analysis and reporting. Common use cases include generating detailed routing reports, calculating standard costs by rolling up resource charges, and performing capacity planning via CRP (Capacity Requirements Planning). A typical query retrieves all resources for a given routing or assembly item. For example:

  • Listing resources for an operation: SELECT resource_seq_num, resource_id, usage_rate_or_amount, basis_type FROM bom_operation_resources WHERE operation_sequence_id = :op_seq_id ORDER BY resource_seq_num;
  • Cost roll-up analysis often joins this table to BOM_OPERATION_SEQUENCES, BOM_BILL_OF_MATERIALS, and CST_ITEM_COSTS.
  • Capacity planning processes, managed by the CRP module, directly consume this data to generate detailed resource hour requirements in the CRP_RESOURCE_HOURS table.

Related Objects

The BOM_OPERATION_RESOURCES table maintains defined foreign key relationships with several other core EBS tables, as documented in the provided metadata.

  • BOM_OPERATION_SEQUENCES: The parent table. The column BOM_OPERATION_RESOURCES.OPERATION_SEQUENCE_ID references BOM_OPERATION_SEQUENCES to define the operation to which the resource belongs.
  • CST_ACTIVITIES: For detailed costing. The column BOM_OPERATION_RESOURCES.ACTIVITY_ID can link a resource to a cost activity.
  • CRP_RESOURCE_HOURS: For planning output. The CRP module populates this child table using the composite foreign key (OPERATION_SEQUENCE_ID, RESOURCE_SEQ_NUM) from BOM_OPERATION_RESOURCES to store planned and simulated resource loads.
