DeepseekETRM - PSA Tables and Views in Oracle EBS 12.1.1/12.2.2

Overview

The DeepseekETRM (Electronic Technical Reference Manual) provides comprehensive documentation on Oracle E-Business Suite (EBS) technical components, including Public Sector Accounting (PSA) tables and views. In Oracle EBS 12.1.1 and 12.2.2, PSA modules leverage a structured database architecture to support government accounting requirements, fund management, and budgetary control.

Core PSA Tables

1. GL_PSA_BUDGETS - Stores budget definitions and control parameters for public sector entities. Key columns include BUDGET_ID, LEDGER_ID, STATUS, and ENCUMBRANCE_FLAG. 2. GL_PSA_BUDGET_PERIODS - Manages fiscal period associations for budgets with PERIOD_ID, BUDGET_ID, and PERIOD_YEAR as critical fields. 3. GL_PSA_FUNDS - Central repository for fund accounting data containing FUND_ID, FUND_NUMBER, FUND_TYPE, and GOVERNMENT_LEVEL_CODE. 4. GL_PSA_ENCUMBRANCES - Tracks financial commitments with ENCUMBRANCE_ID, BUDGET_ID, and ENCUMBRANCE_AMOUNT fields.

Key PSA Views

1. GL_PSA_BUDGETS_V - Combines budget data with ledger information through joins to GL_LEDGERS. 2. GL_PSA_FUNDS_V - Provides enhanced fund reporting by joining GL_PSA_FUNDS with GL_CODE_COMBINATIONS. 3. GL_PSA_ENCUMBRANCE_SUMMARY_V - Aggregates encumbrance data for reporting with calculated available balances.

Technical Architecture

The PSA tables follow Oracle EBS standards with:
  • Naming conventions prefixed with GL_PSA_
  • Foreign key relationships to core GL tables
  • Indexes on frequently queried columns
  • Triggers for data validation
  • API packages (GL_PSA_PUB) for programmatic access

Integration Points

PSA tables integrate with:
  • General Ledger (GL) through ledger_id references
  • Subledger Accounting via SLA integration tables
  • Budgetary Control through GL_BC_PACKETS
  • Financial Reporting using FSG components

Data Flow

The typical PSA data flow involves:
  1. Budget creation in GL_PSA_BUDGETS
  2. Fund setup in GL_PSA_FUNDS
  3. Period definition in GL_PSA_BUDGET_PERIODS
  4. Encumbrance recording in GL_PSA_ENCUMBRANCES
  5. Reporting through PSA views

Customization Considerations

When extending PSA functionality:
  • New columns should follow PSA naming standards
  • Custom triggers must maintain data integrity
  • Views should join to base PSA tables properly
  • APIs should be used instead of direct DML

Performance Optimization

Critical performance factors include:
  • Partitioning large PSA tables by fiscal year
  • Materialized views for complex reports
  • Proper indexing strategy
  • Parallel processing for batch operations

Conclusion

The DeepseekETRM documentation of PSA tables and views provides essential technical guidance for implementing and maintaining public sector accounting functionality in Oracle EBS 12.1.1 and 12.2.2. Understanding these database objects is crucial for customizations, integrations, and performance tuning in government accounting implementations.
