CTRM Accounting Reporting Architecture

This document defines the conceptual architecture of accounting and financial reporting in a CTRM / ERP environment.

The purpose is to provide a standard framework for financial reporting independent of the technical data model.

This architecture will later guide:

  • ERP / CTRM data mapping
  • SQL query design
  • BI reporting layers
  • reconciliation controls
  • auditability

The framework follows commodity trading accounting best practices.


1. Reporting Layers

In a CTRM environment, reporting must be organized into five logical layers. Operational Layer ↓ Subledger Layer ↓ Accounting Layer ↓ Financial Reporting Layer ↓ Management Analytics Layer

Each layer has different users and reporting objectives.


2. Operational Layer

This layer contains trading and operational activity.

Typical objects:

  • contracts
  • trades
  • positions
  • physical deliveries
  • logistics
  • settlements

Reports in this layer are typically operational dashboards.

Examples: Open positions Trade lifecycle Contract exposures Inventory movements

These reports are not accounting reports, but they feed accounting events.


3. Subledger Layer

Subledgers translate operational activity into financial transactions.

Typical subledgers in a CTRM: Accounts Receivable Accounts Payable Inventory Cash / Banking Derivatives Forex

Reports in this layer include: Customer balances Supplier balances Payment status Cash movements Inventory valuation Derivative positions

Subledger reports allow operational reconciliation before data reaches the general ledger.


4. Accounting Layer

This layer represents the official accounting ledger.

It contains: journal entries posting dates accounting accounts currencies documents

Core accounting reports: General ledger Trial balance Journal listing Account movements

These reports represent the single source of truth for financial reporting.


5. Financial Reporting Layer

This layer produces statutory financial statements.

Typical reports: Balance sheet Profit & loss Cash flow statement Comparative financial statements

Characteristics:

  • structured by account hierarchy
  • aligned with accounting standards
  • used for management and external reporting

6. Management Analytics Layer

This layer provides business performance analytics.

Examples: Trading P&L Desk profitability Commodity profitability Margin analysis Risk exposure

Data sources may include:

  • accounting entries
  • positions
  • MTM valuations
  • hedging data

This layer often feeds BI tools and dashboards.


7. Core Accounting Objects

To support reporting, the system must expose a minimal conceptual model.

Journal Entry

Basic accounting object.

Typical attributes: entry_id journal posting_date document_number account currency debit credit description


Accounting Document

Represents the business origin of entries.

Examples: invoice payment bank transaction mtm adjustment fx settlement

Each document may generate multiple journal entries.


8. Accounting Events

Commodity trading systems generate accounting through events.

Examples: Trade confirmation Physical delivery Invoice issuance Payment execution MTM revaluation FX settlement Derivative settlement

Each event generates a defined accounting pattern.

Example: Customer invoice

Debit Accounts Receivable Credit Revenue


9. Realized vs Unrealized Results

A key concept in CTRM reporting is the distinction between: Realized results Unrealized results

Realized P&L

Generated when economic events are completed.

Examples: sale invoice contract settlement derivative settlement fx settlement

Unrealized P&L

Generated by valuation adjustments.

Examples: MTM valuation inventory revaluation open FX exposures

These entries are usually reversed in the following period.


10. Mark-to-Market Reporting

CTRM systems rely heavily on MTM valuation.

Typical reports: MTM valuation by contract MTM valuation by desk MTM valuation by commodity

Accounting representation: Debit / Credit Unrealized P&L Counterpart MTM reserve account


11. Hedge Accounting

Many CTRM systems implement hedge relationships.

Concepts: hedged item hedging instrument hedge effectiveness

Reports include: hedge exposure hedge effectiveness hedge P&L

Accounting depends on the hedge model used.


12. Forex Reporting

Commodity trading often involves multi-currency flows.

Forex reporting usually includes: FX exposures Realized FX results Unrealized FX results FX revaluation

Key accounting processes: currency translation revaluation of open balances FX settlement


13. Cash and Banking Reporting

Cash reports are essential for reconciliation.

Typical reports: Bank ledger Cash position Payment history Bank reconciliation

These reports ensure: ERP balances = bank statements


14. Reconciliation Framework

A CTRM reporting architecture must include reconciliation layers.

Critical reconciliations: Subledger vs General Ledger MTM vs Accounting MTM Positions vs Accounting Inventory Bank vs Accounting Cash

These controls are essential for audit.


15. Multi-Currency Reporting

Commodity trading is inherently multi-currency.

Reports must support: transaction currency functional currency reporting currency

Typical reporting outputs: local currency group currency contract currency


16. Report Parameterization

Most reports should support standard parameters.

Typical parameters: date_from date_to entity account currency counterparty desk commodity contract

Standardization allows consistent reporting behaviour.


17. Export and Integration

Accounting reports must support export formats.

Standard outputs: CSV XLSX PDF API endpoints

This allows integration with: BI tools regulatory reporting external auditors


18. Auditability

All reports must guarantee traceability.

Requirements: source document reference journal entry reference posting date user identification

This ensures audit compliance.


19. Future ERP Mapping

Once the ERP / CTRM data model is available, the next step will be: map reports → tables map reports → fields define SQL views define BI datasets

The current documentation defines the functional blueprint.


20. Summary

The reporting architecture is based on the following layers: Operational Subledger Accounting Financial Reporting Management Analytics

This layered model ensures: clear responsibilities robust reconciliation auditability scalable reporting

It provides the foundation for implementing accounting reporting in a CTRM / ERP open-source platform.
