The GL_ACCT_MAP table in Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 is a critical repository for account mapping rules used in the General Ledger (GL) module. This table stores mappings between source values (such as segments from subledger transactions) and target General Ledger account combinations, facilitating automated journal entry generation. Below is a detailed analysis of its structure, purpose, and functional significance.

Purpose and Functional Role

The GL_ACCT_MAP table enables dynamic account derivation during subledger-to-GL journal creation. It eliminates manual intervention by mapping source attributes (e.g., Inventory Org, Transaction Type) to predefined GL account combinations. This is particularly useful in modules like Accounts Payable (AP), Accounts Receivable (AR), and Inventory (INV), where transactional data must align with GL accounting rules.

Key Columns and Structure

The table's structure includes the following critical columns:
  • APPLICATION_ID: Identifies the source EBS module (e.g., 200 for AP, 222 for AR).
  • SOURCE_TYPE: Specifies the context (e.g., 'INV' for Inventory, 'AP' for Payables).
  • SOURCE_VALUE: The source segment value (e.g., Inventory Org Code).
  • TARGET_VALUE: The mapped GL segment value (e.g., Natural Account).
  • SEGMENT_TYPE: Defines the segment being mapped (e.g., 'ACCOUNT', 'COST_CENTER').
  • ENABLED_FLAG: Activates/deactivates the mapping rule.

Integration with Subledger Accounting

In Oracle EBS 12.1.1/12.2.2, the GL_ACCT_MAP table integrates with the Subledger Accounting (SLA) engine. During journal import, SLA references these mappings to derive accounts dynamically. For example:
  • An AP invoice line with a "Freight" expense type might map to GL account 01-000-543210-0000-000.
  • An Inventory transaction could map to a specific Cost of Goods Sold (COGS) account based on the item category.

Configuration and Maintenance

Mappings are typically configured via:
  • Oracle General Ledger: Navigate to Setup > Financials > Accounting Setup Manager.
  • AD_ZD_SEED.UPGRADE: Used in 12.2.2 for seed data patches.
Administrators must ensure mappings adhere to the Chart of Accounts (COA) structure and are validated via GL_ACCT_MAP_VALIDATE procedures.

Performance and Impact

The table's efficiency directly affects journal generation speed. Indexes on APPLICATION_ID, SOURCE_TYPE, and SOURCE_VALUE optimize query performance. Poorly designed mappings can lead to:
  • Journal errors due to invalid account combinations.
  • Performance degradation during high-volume transaction processing.

Version-Specific Considerations

In EBS 12.2.2, the table may include additional columns for cloud compatibility or enhanced auditing. Cross-validation rules in 12.2.2 also interact with GL_ACCT_MAP to enforce accounting policies.

Conclusion

The GL_ACCT_MAP table is a cornerstone of Oracle EBS's financial architecture, enabling seamless, rule-based account derivation. Its proper configuration ensures accurate GL postings and compliance with organizational accounting standards. Understanding its structure and integration points is essential for functional consultants and system administrators.
