The MTL_SUPPLY_DEMAND_TEMP table in Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 is a critical temporary table used within the Inventory and Supply Chain modules to manage supply and demand data during transaction processing. It serves as a staging area for temporary records before they are processed into permanent tables, ensuring data integrity and performance optimization during complex inventory operations. Below is a detailed breakdown of its structure, purpose, and usage.

Purpose and Functionality

The MTL_SUPPLY_DEMAND_TEMP table acts as an intermediary storage for supply and demand transactions, such as sales orders, purchase orders, transfers, and replenishments. It facilitates real-time inventory visibility by temporarily holding transactional data before it is committed to permanent tables like MTL_SUPPLY or MTL_DEMAND. This temporary storage mechanism improves performance by reducing contention on primary tables during high-volume transactions.

Key Columns and Structure

The table includes columns that capture essential supply and demand attributes, such as:
  • TEMP_ID: A unique identifier for each temporary record.
  • INVENTORY_ITEM_ID: References the item in MTL_SYSTEM_ITEMS_B.
  • ORGANIZATION_ID: Identifies the inventory organization.
  • SUPPLY_DEMAND_TYPE: Distinguishes between supply (e.g., purchase orders) and demand (e.g., sales orders).
  • QUANTITY: The quantity involved in the transaction.
  • DATE_REQUIRED: The date by which the supply or demand is needed.
  • REFERENCE_NUM: Links to the source document (e.g., PO or SO number).
  • PROCESS_FLAG: Indicates whether the record has been processed (e.g., 'Y' or 'N').

Integration with Oracle EBS Modules

The table is utilized across multiple modules:
  • Inventory Management: Tracks pending material movements.
  • Order Management: Temporarily holds sales order demand before allocation.
  • Purchasing: Stores purchase order supply data before processing.
  • MRP (Material Requirements Planning): Supports planning engines by providing transient supply/demand data.

Transaction Workflow

  1. Data Insertion: Transactions populate MTL_SUPPLY_DEMAND_TEMP via APIs or forms.
  2. Processing: Background processes (e.g., INV_TXN_MANAGER) validate and transfer records to permanent tables.
  3. Cleanup: Processed records are purged or archived to maintain performance.

Performance Considerations

To avoid bottlenecks:
  • Indexes on TEMP_ID, PROCESS_FLAG, and REFERENCE_NUM optimize queries.
  • Regular purging of processed records prevents table bloating.
  • Partitioning (in 12.2.2) may be used for high-volume environments.

Customizations and Extensions

While Oracle discourages direct modifications, extensions can be implemented via:
  • Custom APIs to insert/update records.
  • Triggers or PL/SQL logic for additional validation.
  • Concurrent programs to automate cleanup tasks.

Conclusion

The MTL_SUPPLY_DEMAND_TEMP table is a foundational component in Oracle EBS, enabling efficient supply-demand synchronization. Its design ensures transactional integrity while supporting high-performance inventory operations. Understanding its structure and workflow is essential for troubleshooting and optimizing inventory processes in EBS 12.1.1 and 12.2.2.
