# Trade Finance Backlog
This backlog tracks the next development phases for the `trade_finance`
module.
Status values:
```text
todo | in-progress | blocked | done
```
Priority values:
```text
low | medium | high
```
## Phase 1 - Core Ledger Foundation
Goal: stabilize the Trade Finance file, presentation, and movement ledger.
### TF-001 - Validate core model installation
Status: todo
Area: test
Priority: high
Goal:
- Install/update the module in a real Tryton database with dependencies.
- Confirm the new models, views, sequence, menus, and access rules load.
Implementation notes:
- Run the targeted module test suite in an environment with `python-sql` and
the full Tryton dependency stack.
- Fix any XML/view/model registration issue found during module activation.
Validation:
- `python -m unittest modules.trade_finance.tests.test_module`
- Manual module activation/update in a development database.
### TF-002 - Harden posted movement immutability
Status: todo
Area: workflow
Priority: high
Goal:
- Ensure posted presentations and posted movement lines cannot be edited or
deleted through direct writes, nested One2Many writes, or UI actions.
Implementation notes:
- Review `write`, `delete`, and nested child update behavior.
- Keep reversal movements as the only correction path for posted exposure.
Validation:
- Add tests for direct line write/delete after posting.
- Add tests for nested line modification through presentation write.
### TF-003 - Add robust exposure helper methods
Status: todo
Area: model
Priority: high
Goal:
- Provide reusable helpers for exposure by facility limit and by Trade Finance
file.
Implementation notes:
- Keep ledger lines as the source of truth.
- Start with Python helpers; SQL/materialized reporting can come later.
- Include `as_of_date` support for historical exposure.
Validation:
- Tests for current exposure by limit.
- Tests for historical exposure before/after transfer movements.
### TF-004 - Improve limit eligibility validation
Status: todo
Area: model
Priority: high
Goal:
- Validate selected `trade_finance.facility_limit` against bank, currency,
validity dates, financing type, and expected operational status.
Implementation notes:
- Reuse `trade_finance.facility_limit_op_status`.
- Do not create a separate `bank.limit` model.
- Consider whether root global limits should be selectable or whether only
leaf sub-limits should receive movements.
Validation:
- Tests for rejected bank mismatch.
- Tests for rejected currency mismatch.
- Tests for rejected financing type mismatch.
- Tests for rejected operational status mismatch once connected.
## Phase 2 - Basic UX and Operational Entry Points
Goal: make the core usable from operational documents.
### TF-005 - Add contextual Start Financing wizard
Status: todo
Area: workflow
Priority: high
Goal:
- Let users start a Trade Finance presentation from an operational document.
Implementation notes:
- Start with stock shipment and stock move because `stock` is already a module
dependency.
- Use `fields.Reference` on presentation origin.
- Pre-fill date, origin, stage, company, currency, and suggested quantity where
available.
Validation:
- Wizard test from `stock.shipment.in`.
- Manual UI check from shipment form.
### TF-006 - Add purchase contract entry points
Status: todo
Area: workflow
Priority: medium
Goal:
- Start financing from purchase contract and purchase contract line when the
relevant purchase contract module is available.
Implementation notes:
- First identify the actual local model names and module dependency impact.
- Avoid adding a hard dependency until confirmed necessary.
- Prefer optional extension module logic if purchase contract is not part of
the base dependency graph.
Validation:
- Tests only if the dependency is activated in the module test environment.
### TF-007 - Add invoice financing entry point
Status: todo
Area: workflow
Priority: medium
Goal:
- Start or continue financing from receivable/invoice stage.
Implementation notes:
- Confirm whether dependency on `account_invoice` is acceptable.
- Origin should point to `account.invoice`.
- Presentation type should default to invoice financing.
Validation:
- Test default origin and stage from invoice when dependency is enabled.
### TF-008 - Add central exposure summary in the UI
Status: todo
Area: view
Priority: medium
Goal:
- Show current exposure by facility limit on the Trade Finance file.
Implementation notes:
- Use a read-only derived view/model or function fields first.
- Do not store manual exposure balances.
Validation:
- Manual UI check with multiple posted movements.
- Tests for summary values if implemented as model logic.
## Phase 3 - Transfer and Lifecycle Workflow
Goal: support movement between financing stages and limits.
### TF-009 - Add transfer proposal helper
Status: todo
Area: workflow
Priority: high
Goal:
- Generate two movement lines for transfers between facility limits.
Implementation notes:
- Negative line on the source facility limit.
- Positive line on the target facility limit.
- Preserve different haircuts/rates on each line.
Validation:
- Test PREFI to IN_TRANSIT transfer with liquidity gain.
### TF-010 - Track liquidity gain/loss
Status: todo
Area: model
Priority: medium
Goal:
- Calculate liquidity gain/loss when moving collateral between limits with
different haircuts.
Implementation notes:
- Keep this derived from movement lines.
- Store applied haircut on each line for audit.
Validation:
- Test gain when target haircut is lower.
- Test loss when target haircut is higher.
### TF-011 - Add repayment/release presentation support
Status: todo
Area: workflow
Priority: medium
Goal:
- Allow users to release financed exposure partially or fully.
Implementation notes:
- Repayment/release should create negative movement lines.
- Avoid editing original posted movements.
Validation:
- Test partial repayment.
- Test full repayment reduces exposure to zero.
## Phase 4 - Funding Cost Engine
Goal: calculate funding costs from chronological exposure movements.
### TF-012 - Build exposure period calculation
Status: todo
Area: model
Priority: high
Goal:
- Convert dated movement lines into running exposure periods per facility
limit.
Implementation notes:
- Sort by movement date.
- Calculate running balance.
- Build intervals until the next movement date or an explicit end date.
Validation:
- Test one movement.
- Test multiple movements on different dates.
- Test same-day movements.
### TF-013 - Calculate interest/funding cost
Status: todo
Area: model
Priority: high
Goal:
- Calculate funding cost using exposure, applied rate, days, and day-count
basis.
Implementation notes:
- Use values copied onto movement lines at posting time.
- Support `360`, `365`, `ACT/360`, and `ACT/365`.
Validation:
- Tests for 360 and 365 bases.
- Test changing facility cost after posting does not alter historical cost.
### TF-014 - Add funding cost report screen
Status: todo
Area: report
Priority: medium
Goal:
- Provide a user-facing report of funding cost by Trade Finance file and by
facility limit.
Implementation notes:
- Start with a Tryton model/report view.
- Add export later only if needed.
Validation:
- Manual report check.
- Tests for report backing model if applicable.
## Phase 5 - Reporting and Controls
Goal: make exposure auditable and operationally controllable.
### TF-015 - Add current exposure by facility limit report
Status: todo
Area: report
Priority: high
Goal:
- Show exposure grouped by `trade_finance.facility_limit`.
Implementation notes:
- Source data must be posted movement lines.
- Include quantity and signed financed amount.
Validation:
- Test aggregation across multiple Trade Finance files.
### TF-016 - Add historical exposure as-of report
Status: todo
Area: report
Priority: medium
Goal:
- Show exposure at a selected historical date.
Implementation notes:
- Filter movement lines where `movement_date <= as_of_date`.
- Group by facility limit and optionally by Trade Finance file.
Validation:
- Tests around before/after transfer dates.
### TF-017 - Add over-limit checks and alerts
Status: todo
Area: workflow
Priority: medium
Goal:
- Detect when posted exposure exceeds facility limit amount.
Implementation notes:
- Decide whether to block posting or warn first.
- Consider parent/global limit and child sub-limit behavior.
Validation:
- Test over child limit.
- Test over global limit if hierarchical aggregation is implemented.
### TF-018 - Add expired limit controls
Status: todo
Area: workflow
Priority: medium
Goal:
- Highlight or block new exposure on expired limits.
Implementation notes:
- Posting already checks movement date validity.
- Add UI filtering and operational alerts.
Validation:
- Manual UI domain check.
- Tests for posting behavior already covered by core validation.
## Phase 6 - Advanced Operational Integration
Goal: connect financing to the broader commodity workflow.
### TF-019 - Add sale matching support
Status: todo
Area: workflow
Priority: medium
Goal:
- Continue financing lifecycle when goods are matched with sales.
Implementation notes:
- Identify the actual local matching model.
- Add it to origin selection only after confirming dependency/model names.
Validation:
- Scenario test once model dependency is clear.
### TF-020 - Add automatic stage suggestions
Status: todo
Area: workflow
Priority: medium
Goal:
- Suggest finance stage from origin document status.
Implementation notes:
- Keep suggestions editable.
- Implement stage inference per origin model.
Validation:
- Tests per supported origin type.
### TF-021 - Add derived snapshot table if performance requires it
Status: todo
Area: report
Priority: low
Goal:

# Trade Finance Development Guidance
This file captures implementation guidance for the next development steps of
the `trade_finance` module.
It complements `tryton_trade_finance_architecture.md` and should be used as the
practical working note before creating or changing code.
## 1. Important Existing Model Mapping
The architecture document uses the conceptual name `bank.limit`.
In this codebase, do not create a new `bank.limit` model for the Trade Finance
ledger unless there is a later explicit design decision to do so.
Use the existing facility structure instead:
```text
Concept in architecture doc Existing model in this module
--------------------------- -----------------------------
bank.limit trade_finance.facility_limit
bank / banking facility trade_finance.facility
bank reference / provider trade_finance.facility.tfe
limit amount trade_finance.facility_limit.amount
limit currency trade_finance.facility_limit.currency
limit validity trade_finance.facility_limit.date_from/date_to
limit financing type trade_finance.facility_limit.financing_type
limit haircut rules trade_finance.facility_limit_haircut
limit accepted currencies trade_finance.facility_limit_currency
limit cost/rate rules trade_finance.facility_limit_cost
limit operational eligibility trade_finance.facility_limit_op_status
```
Any future presentation ledger line should therefore reference
`trade_finance.facility_limit`, not a hypothetical `bank.limit`.
## 2. Development Principles
- Keep the existing facility/limit model as the contractual source of truth.
- Treat presentation lines as an exposure movement ledger.
- Store signed amounts and signed quantities on movement lines.
- Do not store or manually update current exposure balances as source data.
- Copy applied haircut/rate/cost values onto posted movement lines for audit.
- Use reversal movements for cancellations instead of editing posted movements.
- Keep contextual origin links polymorphic with `fields.Reference`.
- Add new operational start points by extending the reference selection and
action logic, not by adding many foreign keys to a header model.
## 3. Suggested Documentation Structure
Use a small set of focused markdown files under `modules/trade_finance/documentation/`.
Recommended structure:
```text
documentation/
tryton_trade_finance_architecture.md
development_guidance.md
roadmap.md
backlog.md
bugs.md
decisions.md
test_plan.md
```
Purpose of each file:
```text
tryton_trade_finance_architecture.md
Long-form target architecture and conceptual model.
development_guidance.md
Practical implementation rules, mappings to existing models, and local
conventions for developers.
roadmap.md
Ordered development phases. Stable enough to show where the module is going.
backlog.md
Concrete features/tasks not yet scheduled. One item per small deliverable.
bugs.md
Known defects, reproduction notes, expected behavior, and current status.
decisions.md
Architecture decision records. Use for choices that should not be rediscovered
every time, such as using facility_limit instead of bank.limit.
test_plan.md
Targeted validation strategy, scenarios to cover, and commands to run.
```
Do not create every file upfront if it would remain empty. Create them when
there is useful content to record.
## 4. Suggested Item Formats
### Backlog Item
```text
## TF-001 - Short title
Status: todo | in-progress | blocked | done
Area: model | workflow | view | report | test | data
Priority: low | medium | high
Goal:
- What business behavior should exist?
Implementation notes:
- Smallest expected code change.
- Existing model(s) to reuse.
Validation:
- Target test file or scenario.
- Manual check if needed.
```
### Bug Item
```text
## BUG-001 - Short title
Status: open | reproduced | fixed | closed
Severity: low | medium | high | critical
Area: model | workflow | view | report | test | data
Observed:
- What happens now?
Expected:
- What should happen?
Reproduction:
- Minimal steps or test data.
Fix notes:
- Linked commit/test once fixed.
```
### Decision Record
```text
## ADR-001 - Short title
Date: YYYY-MM-DD
Status: proposed | accepted | superseded
Context:
- Why a decision is needed.
Decision:
- What we decided.
Consequences:
- What this enables.
- What tradeoffs remain.
```
## 5. Immediate Next Development Focus
Recommended next implementation sequence:
1. Create the Trade Finance file/header model.
2. Create the presentation/event model.
3. Create the presentation line ledger model linked to
`trade_finance.facility_limit`.
4. Add sequence/configuration for internal Trade Finance references.
5. Add minimal list/form views and access rules.
6. Add targeted tests around creation, references, signed movements, and limit
validity checks.
The first implementation should stay narrow: no funding-cost engine, no
snapshot table, and no automatic exposure summary as source of truth until the
ledger model is stable.
