The MTL_ITEM_LOCATIONS table in Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 is a critical inventory management entity that stores detailed information about subinventory locations within an organization. It serves as a foundational component of Oracle Inventory and Warehouse Management modules, enabling granular tracking of item storage locations. This table maintains a hierarchical relationship with the MTL_SECONDARY_INVENTORIES table, where each record in MTL_ITEM_LOCATIONS represents a specific storage location within a subinventory.

Key Attributes and Structure

The table contains several important columns that define location characteristics:
  • INVENTORY_LOCATION_ID: Primary key identifier for each location
  • ORGANIZATION_ID: Links to the operating unit in HR_ORGANIZATION_UNITS
  • SUBINVENTORY_CODE: Foreign key to MTL_SECONDARY_INVENTORIES
  • SEGMENT1-SEGMENT20: Flexfield segments for location naming
  • DESCRIPTION: Human-readable location description
  • PHYSICAL_LOCATION_CODE: Alternate location identifier
  • PICKING_ORDER: Sequence for picking operations
  • LOCATION_STATUS: Active/Inactive status indicator
  • INVENTORY_LOCATION_TYPE: Classification of location type
  • LOCATION_MAXIMUM_UNITS: Capacity constraint

Functional Relationships

The table integrates with multiple Oracle modules through foreign key relationships:
  • Links to MTL_ONHAND_QUANTITIES for stock balancing
  • References in WMS_LPN_CONTENTS for license plate tracking
  • Association with RCV_TRANSACTIONS for receiving operations
  • Connection to MTL_MATERIAL_TRANSACTIONS for movement history

Business Process Integration

In operational scenarios, the table supports:
  • Warehouse Management: Defines storage locations for putaway rules
  • Inventory Control: Enables cycle counting by location
  • Manufacturing: Stores component issue locations
  • Order Management: Determines picking locations for shipments
  • Cost Accounting: Tracks location-specific valuation

Technical Considerations

Implementation requires attention to:
  • Flexfield configuration for location naming conventions
  • Indexing strategy for performance optimization
  • Data purging policies for historical locations
  • Integration with WMS for advanced location control
  • Validation rules for location capacity constraints

Version-Specific Features

In EBS 12.2.2, enhancements include:
  • Improved integration with Oracle Warehouse Management
  • Support for location-based mobile transactions
  • Enhanced location capacity planning features
  • Additional attributes for 3D bin management
The MTL_ITEM_LOCATIONS table forms the structural backbone for precise inventory localization within Oracle EBS, enabling organizations to implement sophisticated warehouse strategies while maintaining data integrity through its comprehensive constraint network. Proper configuration and utilization of this table are essential for achieving optimal inventory accuracy and operational efficiency in distribution and manufacturing environments.
