# Changelog
## [17.0.1.0.1] - 2025-11-21
### Fixed
- **CRITICAL FIX**: Fixed precision issue where manually entering values like 277,534 would display as 277,534.50
- Overrode `price_unit` field to use 6 decimal places instead of 2 (Product Price precision)
- Removed explicit rounding in onchange methods to preserve maximum precision
- This ensures that manually entered tax excluded and tax included amounts are preserved exactly
### Technical Details
- **Root Cause**: The `price_unit` field was using the "Product Price" decimal precision (2 decimals)
- **Solution**: Override the field definition with `digits=(16, 6)` to allow 6 decimal places
- When you enter 277,534 with quantity 150:
- Old: price_unit = 1850.23 (2 decimals) → recalc = 277,534.50 ❌
- New: price_unit = 1850.226667 (6 decimals) → recalc = 277,534.00 ✅
### Example
Before fix:
- Enter Tax excl: 277,534
- Calculated price_unit: 1850.23 (limited to 2 decimals by field definition)
- Displayed Tax excl: 277,534.50 ❌ (1850.23 × 150)
After fix:
- Enter Tax excl: 277,534
- Calculated price_unit: 1850.226667 (now supports 6 decimals)
- Displayed Tax excl: 277,534.00 ✅ (1850.226667 × 150 = 277,534.0005, rounded to 277,534.00)
### Upgrade Instructions
1. Stop Odoo server
2. Run: `python3 odoo/odoo-bin -c odoo.conf -d YOUR_DB -u vendor_bill_editable_totals --stop-after-init`
3. Start Odoo server
4. Clear browser cache (important!)
5. Test with a vendor bill

# Vendor Bill Editable Totals
## Overview
This Odoo 17 module enables accountants to directly edit the tax excluded (`price_subtotal`) and tax included (`price_total`) amounts on vendor bill invoice lines. When these fields are modified, the system automatically recalculates the unit price (`price_unit`) to maintain exact decimal accuracy with the user-inputted amounts.
This is particularly useful when entering vendor bills where the supplier invoice shows total amounts that don't divide evenly, or when you need to match exact amounts without manually calculating unit prices.
## Features
- ✅ **Direct editing of tax excluded amounts** - Modify `price_subtotal` directly on vendor bill lines
- ✅ **Direct editing of tax included amounts** - Modify `price_total` directly on vendor bill lines
- ✅ **Automatic unit price recalculation** - System calculates `price_unit` to match your entered totals
- ✅ **Decimal precision accuracy** - Maintains exact amounts within configured decimal precision
- ✅ **Multiple tax support** - Correctly handles lines with multiple taxes
- ✅ **Credit note support** - Works with negative values for credit notes and adjustments
- ✅ **Edge case handling** - Graceful handling of zero quantities, no taxes, and other edge cases
- ✅ **Seamless integration** - Works with standard Odoo vendor bill workflows
## Installation
1. Copy the `vendor_bill_editable_totals` folder to your Odoo `addons` directory
2. Update the apps list: Go to **Apps** → Click **Update Apps List**
3. Search for "Vendor Bill Editable Totals"
4. Click **Install**
## Configuration
No configuration is required. The module works out of the box after installation.
The module respects Odoo's existing decimal precision settings:
- Navigate to **Settings** → **Technical** → **Database Structure** → **Decimal Accuracy**
- The "Product Price" precision setting controls the rounding of calculated unit prices
## Usage
### Editing Tax Excluded Amount (price_subtotal)
1. Navigate to **Accounting** → **Vendors** → **Bills**
2. Create a new vendor bill or open an existing draft bill
3. Add or select an invoice line
4. Click on the **Subtotal** field (price_subtotal) in the invoice line
5. Enter the desired tax excluded amount
6. Press Enter or click outside the field
7. The **Unit Price** will automatically recalculate to match your entered amount
**Example:**
```
Quantity: 3
You enter Subtotal: 100.00
System calculates Unit Price: 33.33
Recomputed Subtotal: 99.99 (or 100.00 depending on precision)
```
### Editing Tax Included Amount (price_total)
1. Navigate to **Accounting** → **Vendors** → **Bills**
2. Create a new vendor bill or open an existing draft bill
3. Add or select an invoice line with taxes configured
4. Click on the **Total** field (price_total) in the invoice line
5. Enter the desired tax included amount
6. Press Enter or click outside the field
7. The **Unit Price** will automatically recalculate, accounting for taxes
**Example:**
```
Quantity: 5
Tax: 10%
You enter Total: 550.00
System calculates:
- Subtotal: 500.00 (550.00 / 1.10)
- Unit Price: 100.00 (500.00 / 5)
Recomputed Total: 550.00
```
### Use Cases
#### Use Case 1: Matching Supplier Invoice Totals
**Scenario:** Your supplier invoice shows a line total of €127.50 for 7 items, but the unit price doesn't divide evenly.
**Solution:**
1. Create vendor bill line with quantity: 7
2. Click on the Subtotal field
3. Enter: 127.50
4. System calculates unit price: 18.21 (rounded)
5. The line total will match the supplier invoice exactly
#### Use Case 2: Entering Tax-Included Amounts
**Scenario:** Your supplier invoice shows a total of $1,234.56 including 15% tax for 10 items.
**Solution:**
1. Create vendor bill line with quantity: 10 and 15% tax
2. Click on the Total field
3. Enter: 1234.56
4. System calculates:
- Subtotal: 1073.53
- Unit price: 107.35
5. The line total including tax will match exactly
#### Use Case 3: Credit Notes
**Scenario:** You need to create a credit note for a returned item worth -€50.00.
**Solution:**
1. Create vendor credit note (refund)
2. Add line with quantity: 1
3. Click on the Subtotal field
4. Enter: -50.00
5. System calculates unit price: -50.00
6. Negative values are handled correctly
## Technical Details
### How It Works
The module extends the `account.move.line` model with two `@api.onchange` methods:
1. **`_onchange_price_subtotal()`** - Triggered when price_subtotal is modified
- Validates quantity is not zero
- Calculates: `price_unit = price_subtotal / quantity`
- Applies decimal precision rounding
2. **`_onchange_price_total()`** - Triggered when price_total is modified
- Validates quantity is not zero
- Calculates tax factor from configured taxes
- Derives: `price_subtotal = price_total / (1 + tax_rate)`
- Calculates: `price_unit = price_subtotal / quantity`
- Applies decimal precision rounding
### View Modifications
The module inherits the vendor bill form view (`account.view_move_form`) and makes the following changes:
- Sets `readonly="0"` for `price_subtotal` field
- Sets `readonly="0"` for `price_total` field
- Adds conditional readonly based on:
- Document state (only editable in 'draft' state)
- Document type (only editable for vendor bills and refunds)
### Supported Document Types
The editable fields are available for:
- Vendor Bills (`move_type='in_invoice'`)
- Vendor Credit Notes (`move_type='in_refund'`)
The fields remain readonly for:
- Customer Invoices
- Customer Credit Notes
- Journal Entries
- Posted documents (state != 'draft')
## Limitations
- Fields are only editable in draft state (standard Odoo behavior)
- Only works for vendor bills and vendor credit notes
- Requires quantity to be set before editing totals (to avoid division by zero)
- Minor rounding differences may occur due to decimal precision limits
## Error Handling
### Division by Zero
If you attempt to edit price_subtotal or price_total when quantity is zero, you'll see an error:
```
Cannot calculate unit price: quantity must be greater than zero
```
**Solution:** Set the quantity to a non-zero value before editing the total fields.
### Precision Rounding
Due to decimal precision limits, there may be minor differences (typically < 0.01) between your entered amount and the recomputed amount. This is normal and expected behavior.
**Example:**
```
You enter: 100.00
Quantity: 3
Calculated unit price: 33.333333...
Rounded unit price: 33.33 (2 decimal places)
Recomputed subtotal: 99.99
```
## Testing
The module includes comprehensive test coverage:
### Property-Based Tests
- Price subtotal calculation accuracy
- Quantity preservation during modifications
- Round-trip accuracy for price_subtotal
- Round-trip accuracy for price_total with taxes
- Decimal precision compliance
### Unit Tests
- Zero quantity error handling
- Negative values (credit notes)
- No taxes scenario
- Single tax calculation
- Multiple taxes calculation
- View configuration
### Integration Tests
- Full workflow: create → modify → save → verify

# Integration Tests for Vendor Bill Editable Totals
## Overview
This document describes the integration tests implemented for the `vendor_bill_editable_totals` module.
## Test Coverage
The integration tests verify the following workflows and requirements:
### 1. Full Workflow - Modify price_subtotal (Requirement 4.3)
- Creates a vendor bill with invoice lines
- Modifies the `price_subtotal` field
- Verifies that `price_unit` is automatically recalculated
- Saves the bill and verifies persistence
- Validates that `price_total` is correctly computed with taxes
### 2. Full Workflow - Modify price_total (Requirement 4.3)
- Creates a vendor bill with invoice lines and taxes
- Modifies the `price_total` field
- Verifies that `price_unit` is automatically recalculated
- Ensures `price_subtotal` is correctly derived from `price_total`
- Saves the bill and verifies persistence
### 3. Multiple Lines Workflow (Requirement 4.3)
- Creates a vendor bill with multiple invoice lines
- Modifies different fields on different lines
- Verifies that each line is calculated independently
- Ensures no interference between lines
### 4. Compatibility with Standard Validations (Requirement 4.3)
- Verifies that standard Odoo validations still work
- Tests that standard compute methods function correctly
- Ensures the module doesn't break existing Odoo behavior
- Validates that bills can be saved after modifications
### 5. Refund Workflow (Requirement 4.3)
- Creates a vendor refund (credit note)
- Tests with negative values
- Verifies calculations work correctly with negative amounts
- Ensures refunds can be saved
### 6. No Interference with Other Move Types (Requirement 4.2)
- Creates a customer invoice (out_invoice)
- Attempts to modify totals
- Verifies that the module only affects vendor bills
- Ensures customer invoices are not affected
## Running the Tests
### Standalone Tests
The standalone integration tests can be run without a full Odoo database:
```bash
python3 customaddons/vendor_bill_editable_totals/tests/run_integration_tests.py
```
### Full Odoo Integration Tests
For complete integration testing with Odoo's test framework:
```bash
python3 odoo/odoo-bin -c odoo.conf --test-enable --stop-after-init \
-d odoo17 -u vendor_bill_editable_totals --log-level=test
```
Or to run only the integration tests:
```bash
python3 odoo/odoo-bin -c odoo.conf --test-enable --stop-after-init \
-d odoo17 --test-tags vendor_bill_editable_totals.test_integration
```
## Test Files
- `test_integration.py` - Full Odoo integration tests using TransactionCase
- `run_integration_tests.py` - Standalone test runner with mock objects
## Test Results
All integration tests pass successfully:
- ✓ Full workflow - modify price_subtotal
- ✓ Full workflow - modify price_total
- ✓ Multiple lines workflow
- ✓ Compatibility with standard validations
- ✓ Refund workflow
- ✓ No interference with other move types
## Requirements Validated
These integration tests validate the following requirements:
- **Requirement 4.2**: Module doesn't interfere with standard Odoo flows
- **Requirement 4.3**: Standard Odoo validations and computations work correctly
## Notes
The integration tests complement the existing test suite:
- **Unit tests** (`test_edge_cases.py`) - Test specific scenarios and edge cases
- **Property-based tests** - Test universal properties across random inputs
- **Integration tests** - Test full workflows from creation to save
- **View tests** (`test_view_configuration.py`) - Test UI configuration
Together, these tests provide comprehensive coverage of the module's functionality.
