The AHL_RT_OPER_MATERIALS table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical data structure within the Oracle Advanced Service Online (ASO) module, specifically supporting the Service and Depot Repair functionality. This table stores detailed information about materials required for repair operations, facilitating efficient service management, inventory tracking, and cost control in service-oriented environments. Below is a detailed technical and functional analysis of this table.

Functional Overview

The AHL_RT_OPER_MATERIALS table is part of the Service Request (SR) and Depot Repair workflows in Oracle EBS. It maintains a mapping between repair operations (defined in AHL_ROUTE_OPERATIONS) and the materials (items) consumed during those operations. This linkage ensures accurate material planning, requisitioning, and cost attribution in repair processes. Key functional aspects include:

  • Material Association: Links repair operations to specific inventory items, ensuring the right parts are available for service tasks.
  • Quantity Tracking: Defines the standard quantity of materials required per operation, aiding in demand forecasting.
  • Cost Management: Supports cost calculation by associating material usage with repair operations, enabling accurate service pricing.
  • Integration with Inventory: Interfaces with Oracle Inventory (INV) to validate item availability and trigger replenishment workflows.

Technical Structure

The table's schema includes columns that capture operational, material, and transactional attributes. Key columns and their purposes are:

Column Name Data Type Description
ROUTE_OPERATION_ID NUMBER Foreign key to AHL_ROUTE_OPERATIONS, identifying the repair operation.
INVENTORY_ITEM_ID NUMBER References MTL_SYSTEM_ITEMS_B, specifying the material used.
ORGANIZATION_ID NUMBER Identifies the inventory organization owning the item (links to HR_ORGANIZATION_UNITS).
QUANTITY NUMBER Standard quantity of the material required per operation.
UOM_CODE VARCHAR2 Unit of measure for the material (e.g., EA, KG).
OBJECT_VERSION_NUMBER NUMBER Used for optimistic locking and concurrency control.

Integration Points

The table interacts with multiple Oracle EBS modules:

  • Oracle Inventory (INV): Validates item existence, UOM compatibility, and availability.
  • Oracle Purchasing (PO): Triggers requisitions for materials if stock is insufficient.
  • Oracle Cost Management (CST): Provides data for service cost roll-ups and profitability analysis.
  • Oracle Work in Process (WIP): Supports material issuance for complex repair workflows.

Key Business Processes

The table enables the following business processes:

  1. Repair Planning: Technicians reference material requirements during service order creation.
  2. Material Reservation: Items are reserved in inventory upon operation scheduling.
  3. Cost Accrual: Material costs are attributed to service orders for financial reporting.
  4. Compliance Reporting: Tracks material usage for regulatory and audit purposes.

Customization Considerations

While the table is seeded by Oracle, common extensions include:

  • Adding custom columns (e.g., SUPPLIER_CODE) via descriptive flexfields (DFFs).
  • Implementing triggers to enforce business rules (e.g., minimum stock levels).
  • Integrating with third-party procurement systems via APIs.

Conclusion

The AHL_RT_OPER_MATERIALS table is a pivotal component in Oracle EBS Service and Depot Repair, bridging operations, materials, and financials. Its design ensures granular tracking of repair-related material consumption, directly impacting service efficiency, cost accuracy, and inventory optimization. Organizations leveraging this table should adhere to Oracle's data governance guidelines to maintain integrity across interconnected modules.
