The MTL_RESERVATIONS_INTERFACE table in Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 serves as a critical interface table for processing inventory reservations. It acts as a staging area where reservation data is temporarily stored before being validated and transferred to the main reservation tables (MTL_RESERVATIONS and related entities). This table is primarily utilized in scenarios involving bulk data imports, integrations with external systems, or complex reservation workflows that require intermediate processing before final commitment to the inventory system.

Key Features and Purpose

The MTL_RESERVATIONS_INTERFACE table enables asynchronous processing of reservation requests, ensuring data integrity and validation before permanent storage. It supports both manual and automated reservation entries, allowing organizations to handle high-volume transactions efficiently. Common use cases include:
  • Bulk reservations for manufacturing or project requirements
  • Integration with third-party warehouse management systems
  • Complex reservation scenarios requiring additional validation logic
  • Error handling for reservation transactions that fail initial validation

Table Structure and Key Columns

The table contains numerous columns that map to reservation attributes, including:
  • RESERVATION_ID: Unique identifier for the interface record
  • INVENTORY_ITEM_ID: References the reserved item
    • ORGANIZATION_ID: Identifies the inventory organization
  • DEMAND_SOURCE_TYPE_ID: Indicates the reservation purpose (e.g., sales order, work order)
  • DEMAND_SOURCE_HEADER_ID: Links to the source document header
  • DEMAND_SOURCE_LINE_ID: Links to the source document line
  • QUANTITY: The amount to be reserved
  • UOM_CODE: Unit of measure for the quantity
  • STATUS: Tracks processing state (PENDING, PROCESSED, ERROR)
  • PROCESS_FLAG: Controls interface processing (Y/N)
  • ERROR_CODE/ERROR_EXPLANATION: Capture validation failures

Processing Workflow

The standard processing flow involves:
  1. Data insertion into the interface table with PROCESS_FLAG='N'
  2. Execution of the reservation interface concurrent program
  3. Validation against business rules (availability, dates, etc.)
  4. Successful records: Transfer to main reservation tables with STATUS='PROCESSED'
  5. Failed records: Marked with STATUS='ERROR' and error details populated

Technical Considerations

For optimal performance in EBS 12.1.1 and 12.2.2:
  • Indexes on key columns (RESERVATION_ID, INVENTORY_ITEM_ID, ORGANIZATION_ID) are critical
  • Regular purging of processed records is recommended
  • The interface program can be scheduled or run on-demand
  • Custom validation logic can be added through API hooks

Integration Points

The table interacts with several Oracle Inventory modules:
  • Inventory Management for availability checks
  • Order Management for sales order reservations
  • Manufacturing for work order material reservations
  • Projects for project inventory requirements

Best Practices

Implementation should consider:
  • Data validation before interface table insertion
  • Monitoring for stuck records (PROCESS_FLAG='Y' but not processed)
  • Error handling procedures for failed reservations
  • Performance tuning for high-volume environments
The MTL_RESERVATIONS_INTERFACE table provides a robust mechanism for managing complex reservation scenarios in Oracle EBS, offering flexibility while maintaining data integrity through its staged processing approach.
