The MTL_RESERVATIONS table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical repository for managing inventory reservations. It stores detailed records of reserved inventory items, ensuring accurate tracking of material allocations across various business processes such as sales orders, work orders, and internal transfers. This table is part of the Oracle Inventory module and plays a pivotal role in maintaining inventory integrity by preventing over-commitment of stock.

Structure and Key Columns:
The MTL_RESERVATIONS table contains several key columns that define reservation attributes:

• RESERVATION_ID: Primary key, uniquely identifying each reservation.
• INVENTORY_ITEM_ID: References the item being reserved, linked to MTL_SYSTEM_ITEMS_B.
• ORGANIZATION_ID: Specifies the inventory organization where the item is reserved.
• DEMAND_SOURCE_TYPE_ID: Indicates the source document type (e.g., sales order, work order).
• DEMAND_SOURCE_HEADER_ID and DEMAND_SOURCE_LINE_ID: Reference the header and line IDs of the source document.
• QUANTITY: The reserved quantity.
• DATE_REQUIRED: The date by which the reservation is needed.
• STATUS: Tracks reservation status (e.g., "Reserved," "Backordered").

Functional Role:
The table supports core inventory processes:

1. Order Management Integration: Reservations for sales orders ensure items are allocated before shipment.
2. Manufacturing: Work orders reserve components to prevent shortages during production.
3. Transfer Reservations: Facilitates inter-organization transfers by earmarking items.
4. Back-to-Back Processing: Links purchase requisitions to sales orders via reservations.

Reservations are automatically created, modified, or deleted through Oracle workflows, such as order entry or pick release.

Technical Considerations:

• Indexes: Key indexes include MTL_RESERVATIONS_N1 (on INVENTORY_ITEM_ID, ORGANIZATION_ID) and MTL_RESERVATIONS_N2 (on demand source fields) for performance optimization.
• Concurrency: Oracle uses row-level locking to manage simultaneous reservation updates.
• Purge: Historical reservations can be archived using INV_RESERVATION_PURGE concurrent program.

Customization and Extensions:
While the table is primarily managed by Oracle standard APIs (e.g., INV_RESERVATION_PUB), customizations may involve:

• Triggers to enforce business rules during reservation creation.
• Extensions to capture additional attributes via descriptive flexfields.
• Integration with third-party systems using Oracle's Open Interfaces.

Conclusion:
The MTL_RESERVATIONS table is foundational for inventory allocation in Oracle EBS. Its design ensures traceability, prevents stock conflicts, and supports complex supply chain scenarios. Proper understanding of its structure and integration points is essential for effective inventory management and system customization.
