The MTL_TXN_REQUEST_LINES table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical transactional entity within the Inventory Management module. It stores detailed line-level information for material transaction requests, which are used to initiate and track inventory movements, adjustments, and transfers. This table works in conjunction with MTL_TXN_REQUEST_HEADERS, where the header table contains summary-level data, while the lines table captures granular transaction details. Below is a detailed analysis of its structure, functionality, and integration within Oracle EBS.

Purpose and Functionality

The MTL_TXN_REQUEST_LINES table serves as a staging area for pending inventory transactions before they are processed into the MTL_MATERIAL_TRANSACTIONS table. It supports various inventory operations, including:

• Issue Transactions: Movement of items from inventory to work orders, projects, or other destinations.
• Transfer Transactions: Movement between subinventories, organizations, or locations.
• Adjustments: Quantity or value corrections for inventory items.
• Receipts: Recording inbound material flows.

Each line represents a distinct item or lot/serial combination, ensuring traceability and compliance with inventory controls.

Key Columns and Relationships

The table includes essential columns to define transaction attributes:

• REQUEST_LINE_ID: Primary key, uniquely identifying each line.
• HEADER_ID: Foreign key linking to MTL_TXN_REQUEST_HEADERS.
• INVENTORY_ITEM_ID: References MTL_SYSTEM_ITEMS_B to identify the item.
• ORGANIZATION_ID: Specifies the inventory organization.
• QUANTITY: The amount to be transacted.
• UOM_CODE: Unit of measure for the transaction.
• SUBINVENTORY_CODE: Source or destination subinventory.
• LOCATOR_ID: Specific storage location within a subinventory.
• LOT_NUMBER/SERIAL_NUMBER: For lot/serial-controlled items.
• PROCESS_FLAG: Indicates whether the line is pending ('N'), processed ('Y'), or errored ('E').
• TRANSACTION_TYPE_ID: References MTL_TRANSACTION_TYPES to define the transaction type.

Integration with Other Modules

The table integrates with multiple Oracle EBS modules:

• Cost Management: Links to CST_ITEM_COSTS for cost calculations.
• Work in Process (WIP): References WIP_ENTITIES for job/schedule-based issues.
• Order Management: Ties to OE_ORDER_LINES for sales order fulfillment.
• Procurement: Connects to PO_HEADERS/LINES for purchase order receipts.

Processing Workflow

Transaction requests follow a structured workflow:

1. Data is inserted into MTL_TXN_REQUEST_LINES via forms, APIs, or interfaces.
2. The INV_TXN_MANAGER_PUB API validates and processes lines with PROCESS_FLAG='N'.
3. Upon successful processing, lines are updated to PROCESS_FLAG='Y', and corresponding records are created in MTL_MATERIAL_TRANSACTIONS and MTL_ONHAND_QUANTITIES.
4. Errors trigger notifications via MTL_INTERFACE_ERRORS for correction.

Customization and Extensions

Organizations often extend the table's functionality by:

• Adding custom columns via Descriptive Flexfields (DFFs).
• Developing custom APIs to automate transaction creation.
• Implementing triggers or workflows for approval routing.

Conclusion

The MTL_TXN_REQUEST_LINES table is foundational for inventory transaction management in Oracle EBS. Its design ensures flexibility, auditability, and integration across supply chain processes. Proper understanding of its schema and workflows is essential for configuring and troubleshooting inventory operations in EBS 12.1.1 or 12.2.2.
