Overview

The WIP_OPERATION_RESOURCES table is a core transactional table within the Oracle E-Business Suite Work in Process (WIP) module. It serves as the definitive repository for all resource requirements assigned to specific manufacturing operations on discrete jobs, repetitive schedules, and flow schedules. The table's primary role is to define the detailed resource consumption plan for a production operation, linking a work order operation (WIP_OPERATIONS) to a defined resource (BOM_RESOURCES) and, optionally, a costing activity (CST_ACTIVITIES). This data is essential for capacity planning, detailed scheduling, shop floor execution, and the subsequent accounting of resource costs, forming a critical link between the bill of materials, routing, and actual production transactions.

Key Information Stored

The table's structure is designed to uniquely identify a resource requirement within the context of a specific manufacturing entity and operation. Its primary key is a composite of WIP_ENTITY_ID, OPERATION_SEQ_NUM, RESOURCE_SEQ_NUM, and REPETITIVE_SCHEDULE_ID. Key columns include WIP_ENTITY_ID, which identifies the specific job or schedule; OPERATION_SEQ_NUM, which denotes the operation sequence; and RESOURCE_SEQ_NUM, which sequences multiple resources within a single operation. The RESOURCE_ID column holds a foreign key to BOM_RESOURCES, defining the resource (e.g., a machine, labor, or tool) required. Other critical columns include USAGE_RATE_OR_AMOUNT and BASIS_TYPE, which determine how the resource is consumed (e.g., per item or per lot), and ACTIVITY_ID, which links to CST_ACTIVITIES for overhead cost assignment.

Common Use Cases and Queries

This table is central to numerous operational and analytical processes. Common use cases include generating detailed work instructions for shop floor personnel, calculating planned resource load for capacity analysis, and providing the basis for variance reporting by comparing planned versus actual resource usage. A typical query might retrieve all resource requirements for a specific job to create a pick list or analyze cost: SELECT wor.resource_id, br.resource_code, wor.usage_rate_or_amount, wor.basis_type FROM wip_operation_resources wor, bom_resources br WHERE wor.wip_entity_id = :p_job_id AND wor.resource_id = br.resource_id ORDER BY wor.operation_seq_num, wor.resource_seq_num;. For repetitive lines, analysts often query aggregate planned resource consumption across a schedule for a given period to assess line loading.

Related Objects

As indicated by the foreign key relationships, WIP_OPERATION_RESOURCES is deeply integrated within the WIP and Costing modules. Its primary parent table is WIP_OPERATIONS, which defines the operation itself. It references BOM_RESOURCES for resource master data and CST_ACTIVITIES for costing. Crucially, it is a parent table to WIP_OPERATION_RESOURCE_USAGE, which records actual resource transactions, and WIP_COST_TXN_INTERFACE, which is the interface table for posting resource cost transactions to Cost Management. This network of relationships underscores its position as a pivotal hub connecting planning, execution, and accounting data flows.
