The MTL_TRANSACTION_LOTS_TEMP table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical temporary table used within the Inventory and Cost Management modules to store lot-level transaction details before they are permanently committed to the main transaction tables. This table plays a pivotal role in ensuring data integrity during complex inventory transactions, particularly those involving lot-controlled items. Below is a detailed breakdown of its purpose, structure, and functionality.

Purpose and Context

The MTL_TRANSACTION_LOTS_TEMP table acts as a staging area for lot-specific attributes during inventory transactions such as receipts, issues, transfers, and adjustments. It temporarily holds lot information—such as lot numbers, expiration dates, and quantities—while the system validates and processes the transaction. This intermediate step prevents data corruption in primary tables (MTL_TRANSACTION_LOTS_INTERFACE, MTL_MATERIAL_TRANSACTIONS) by ensuring all validations (e.g., lot uniqueness, expiration date checks) are completed before final posting.

Key Columns and Structure

The table's schema includes columns essential for lot tracking:

• TRANSACTION_TEMP_ID: Foreign key linking to MTL_TRANSACTIONS_TEMP, associating lot data with the parent transaction.
• LOT_NUMBER: Unique identifier for the lot.
• TRANSACTION_QUANTITY: Quantity involved in the transaction.
• PRIMARY_QUANTITY: Quantity in the item's primary unit of measure.
• SERIAL_TRANSACTION_TEMP_ID: Links to serialized items if applicable.
• EXPIRATION_DATE: Critical for perishable or time-sensitive items.
• ATTRIBUTE_CATEGORY/ATTRIBUTE_COLUMNS: Flexfields for custom lot attributes.

Workflow Integration

The table is integral to the following workflows:

1. Transaction Initiation: When a user submits a lot-controlled transaction (e.g., via forms or APIs), data is first written to MTL_TRANSACTION_LOTS_TEMP.
2. Validation: The Inventory module validates lot attributes (e.g., ensuring the lot exists, checking expiration dates) against business rules.
3. Processing: Upon validation, the data is moved to permanent tables (MTL_TRANSACTION_LOTS), and cost updates are triggered if applicable.
4. Cleanup: Temporary records are purged post-commit or upon transaction failure.

Technical Considerations

• Performance: Indexes on TRANSACTION_TEMP_ID and LOT_NUMBER optimize joins with parent tables.
• Concurrency: The table supports high-volume transactions by isolating in-progress data from committed records.
• Custom Extensions: Organizations often extend functionality via triggers or APIs to enforce additional lot validations.

Common Use Cases

• Receiving: Captures lot details during PO or RMA receipts.
• Cycle Counting: Temporarily stores lot adjustments pending approval.
• Inter-Org Transfers: Manages lot attributes during stock movements.

Conclusion

The MTL_TRANSACTION_LOTS_TEMP table is a foundational component of Oracle EBS's lot control framework, ensuring transactional accuracy and auditability. Its design aligns with Oracle's modular architecture, enabling seamless integration with core inventory processes while maintaining flexibility for customizations. Understanding its role is essential for troubleshooting lot-related issues or extending functionality in implementations requiring rigorous lot tracking.
