The PA_ALLOC_RUN_GL_DET table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical data structure within the Project Accounting (PA) module. It stores detailed General Ledger (GL) accounting entries generated during the allocation process, which is used to distribute shared costs across multiple projects or tasks. This table serves as an intermediary between the allocation engine and the GL, ensuring accurate financial postings while maintaining auditability and traceability.

Purpose and Functionality

The primary purpose of PA_ALLOC_RUN_GL_DET is to record the detailed accounting entries resulting from allocation runs. When the allocation engine processes cost distributions (e.g., overhead, shared resources), it generates debits and credits that must be posted to the GL. This table captures those entries before they are transferred to the GL interface tables (GL_INTERFACE or GL_JE_LINES). It acts as a staging area, allowing validation and reconciliation before final posting.

Key Columns and Relationships

The table includes columns such as:
  • ALLOC_RUN_ID: Links to PA_ALLOC_RUNS, identifying the allocation batch.
  • ALLOC_RUN_GL_DET_ID: Primary key for the table.
  • PROJECT_ID/TASK_ID: References to PA_PROJECTS and PA_TASKS for project-specific allocations.
  • GL_PERIOD: Accounting period for the entry.
  • CODE_COMBINATION_ID: Foreign key to GL_CODE_COMBINATIONS, defining the accounting flexfield.
  • AMOUNT: The monetary value of the allocation (debit/credit).
  • STATUS_FLAG: Indicates whether the entry is processed (e.g., 'P' for Posted, 'U' for Unposted).
The table has foreign key relationships with PA_ALLOC_RUNS, PA_PROJECTS, and GL_CODE_COMBINATIONS, ensuring referential integrity.

Integration with GL and Allocation Process

During allocation execution, the system:
  1. Generates allocation lines in PA_ALLOC_RUN_GL_DET based on predefined rules (e.g., weight-based, percentage-based).
  2. Validates entries against GL accounting rules (e.g., valid CCIDs, open periods).
  3. Updates the STATUS_FLAG upon successful GL interface transfer.
The data is then pushed to GL via standard interfaces, ensuring alignment with fiscal policies.

Audit and Reporting

The table supports audit trails by retaining granular details of allocation postings. Custom reports often join this table with PA_ALLOC_RUNS and GL_CODE_COMBINATIONS to analyze allocation accuracy or troubleshoot discrepancies.

Technical Considerations

In EBS 12.2.2, the table may leverage Oracle's Online Patching (ADOP) features, allowing maintenance without downtime. Performance tuning (e.g., indexing on ALLOC_RUN_ID, STATUS_FLAG) is recommended for large-scale implementations.

Conclusion

PA_ALLOC_RUN_GL_DET is a foundational component for cost allocation in Oracle Projects, bridging project accounting with general ledger. Its design ensures compliance, transparency, and scalability for enterprise financial operations.
