# 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.
