The OKL.OKL_TXL_AP_INV_LNS_ALL_B table is a critical component within Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2, specifically designed for the Oracle Lease and Finance Management (OKL) module. This table serves as the base table for storing transactional data related to invoice lines in the Accounts Payable (AP) integration process. It plays a pivotal role in managing lease-related financial transactions, ensuring seamless data flow between lease contracts and payable invoices.

Table Structure and Key Columns

The table structure comprises columns that capture essential attributes of invoice lines, including:
  • ID: Primary key identifier for the invoice line record.
  • INVOICE_ID: References the parent invoice header in OKL_TXL_AP_INV_HDRS_ALL_B.
  • LINE_NUMBER: Sequential number identifying the line within an invoice.
  • AMOUNT: Monetary value of the invoice line.
  • CURRENCY_CODE: Currency in which the amount is denominated.
  • DESCRIPTION: Textual description of the invoice line item.
  • ASSET_ID: Optional reference to leased assets, linking to OKL_ASSETS_B.
  • CONTRACT_ID: Foreign key to OKL_K_HEADERS_B, associating the line with a lease contract.
  • CREATED_BY, CREATION_DATE, LAST_UPDATED_BY, LAST_UPDATE_DATE: Standard Oracle audit columns.
  • OBJECT_VERSION_NUMBER: Used for optimistic locking in OAF pages.

Functional Role in Lease Management

This table acts as an intermediary between lease contracts (OKL_K_HEADERS_B) and AP invoice lines (AP_INVOICE_LINES_ALL). Key functionalities include:
  1. Lease Payment Processing: Captures line-level details of vendor invoices for lease-related payments (e.g., maintenance, insurance).
  2. Asset Cost Allocation: When invoice lines pertain to leased assets, the ASSET_ID enables cost tracking per asset.
  3. Multi-Org Support: Includes ORG_ID for multi-organization access control.
  4. Integration with AP Module: Data from this table feeds into Oracle Payables via interface tables like AP_INVOICE_LINES_INTERFACE.

Technical Considerations

  • Indexes: Typically indexed on ID, INVOICE_ID, and CONTRACT_ID for performance.
  • Views: Often accessed through views like OKL_TXL_AP_INV_LNS_ALL which adds language-specific translations.
  • APIs: Modifications should use OKL public APIs rather than direct DML to maintain data integrity.
  • Partitioning: In high-volume implementations, partitioning by ORG_ID or date ranges may be implemented.

Customization and Extension

The table supports flexfields for custom attributes:
  • Descriptive Flexfields (DFF): Allow adding context-sensitive fields.
  • Key Flexfields (KFF): Rarely used on this table but configurable if needed.

Data Flow Example

A typical workflow involves:
  1. Lease contract creation in OKL
  2. Vendor invoice entry via OKL screens
  3. Line details stored in OKL_TXL_AP_INV_LNS_ALL_B
  4. Interface program transfers data to AP
  5. Payment processing in Payables

Version-Specific Notes

Between 12.1.1 and 12.2.2:
  • Column structure remains largely consistent
  • 12.2.2 may include additional indexes for cloud-optimized performance
  • Online patching (Edition-Based Redefinition) in 12.2.2 affects how updates are applied
This table exemplifies Oracle's approach to industry-specific verticals in EBS, providing specialized data structures for lease management while maintaining integration points with core financial modules.
