The WIP_EAM_WORK_REQUESTS table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical data structure within the Enterprise Asset Management (EAM) module, specifically designed to manage work requests for maintenance activities. Work requests serve as preliminary notifications for potential maintenance work and are often converted into work orders after approval. This table stores essential metadata and transactional data related to these requests, facilitating asset lifecycle management, maintenance planning, and operational efficiency. ### **Key Attributes of WIP_EAM_WORK_REQUESTS** The table contains several key columns that define the work request lifecycle: - **WORK_REQUEST_ID**: A unique identifier for each work request, typically generated via a sequence. - **ORGANIZATION_ID**: Links the work request to an inventory organization, ensuring proper segregation of data. - **REQUEST_NUMBER**: A user-friendly identifier, often auto-generated based on a numbering schema. - **STATUS**: Reflects the current state of the work request (e.g., Draft, Pending Approval, Approved, Rejected, or Closed). - **REQUEST_DATE**: The date when the request was created. - **REQUESTED_BY**: The user or employee who initiated the request. - **ASSET_NUMBER**: References the asset requiring maintenance, linking to the MTL_EAM_ASSETS table. - **PRIORITY**: Indicates urgency (e.g., High, Medium, Low), influencing scheduling decisions. - **DESCRIPTION**: A detailed explanation of the maintenance need. - **WORK_ORDER_TYPE**: Specifies whether the request will convert to a corrective, preventive, or other type of work order. - **APPROVED_FLAG**: A Boolean field indicating whether the request has been approved for conversion to a work order. - **DEPARTMENT_ID**: Associates the request with a department for cost tracking and responsibility assignment. ### **Integration with Other Modules** The WIP_EAM_WORK_REQUESTS table integrates with multiple Oracle EBS modules: 1. **Inventory Management (INV)**: Validates asset numbers and spare parts availability. 2. **Work in Process (WIP)**: Facilitates the conversion of approved requests into work orders via the WIP_EAM_WORK_ORDERS table. 3. **Purchasing (PO)**: Links to requisitions if external procurement is needed for parts or services. 4. **Human Resources (HR)**: Tracks labor assignments via the REQUESTED_BY and DEPARTMENT_ID fields. ### **Business Process Flow** 1. **Creation**: A user submits a work request, populating mandatory fields like asset number, description, and priority. 2. **Approval**: Supervisors review and approve/reject requests via workflows, updating the STATUS and APPROVED_FLAG. 3. **Conversion**: Approved requests are converted into work orders, with data migrated to WIP_EAM_WORK_ORDERS. 4. **Execution**: Maintenance teams execute the work, updating statuses and recording labor/material usage. 5. **Closure**: Completed requests are closed, and historical data is retained for reporting. ### **Technical Considerations** - **Indexes**: Key columns like WORK_REQUEST_ID, ASSET_NUMBER, and ORGANIZATION_ID are indexed for performance. - **APIs**: Oracle provides PL/SQL APIs (e.g., EAM_WORK_REQUEST_PUB) for programmatic CRUD operations. - **Audit Trails**: Timestamp columns (CREATION_DATE, LAST_UPDATE_DATE) track changes for compliance. ### **Reporting and Analytics** The table supports EAM dashboards and reports, enabling analysis of: - Request volumes by asset, department, or priority. - Approval cycle times. - Conversion rates from requests to work orders. ### **Conclusion** The WIP_EAM_WORK_REQUESTS table is a foundational component of Oracle EBS EAM, streamlining maintenance workflows from request initiation to execution. Its structured schema ensures data integrity, while integrations with other modules provide end-to-end visibility into asset maintenance processes.
