Fixed:
- Removed old getAccountMappings() method on line 615
- Kept the new version that joins with chart of accounts
- This fixes the 'Cannot redeclare' PHP Fatal error
The new method properly retrieves account labels from Dolibarr's accounting_account table.
Fixed:
- Added missing getAccountMappings() method to DeclarationTVA class
- Joins with Dolibarr's accounting_account table to get labels
- Retrieves account labels from chart of accounts (llx_accounting_account)
- Falls back to stored label if chart of accounts label not available
- Returns array with rowid, ca3_line, account_code, account_label, vat_rate, is_active
This fixes the issue where account labels were not showing in dropdown panels.
Fixed:
- Grouped BASE and VAT accounts separately for lines 08, 09, 9B
- Added clear section headers: 'Base Accounts (Sales)' and 'VAT Accounts'
- Improved visual organization of account breakdown
- Removed debugging code
- Added translations for new section headers
This ensures users can clearly see which accounts contribute to base amounts vs VAT amounts for the special lines.
Fixed:
- Updated getCA3LineDetails() to handle special cases for lines 08, 09, 9B
- These lines have _BASE and _VAT suffixes in the database
- Added proper matching logic for both normal lines and special cases
- Added debugging to AJAX endpoint and backend method
- Added error logging to trace mapping issues
This should fix the issue where only A1 works but other lines show no accounts.
Features added:
- New getCA3LineDetails() method in DeclarationTVA class
- New declarationtva_line_details.php page for detailed view
- All CA-3 line codes are now clickable in declaration view
- Detailed breakdown shows:
* Account codes and labels
* Base amounts, VAT amounts, total amounts
* Mapping types (A1, 08_BASE, 08_VAT, etc.)
* Calculated totals vs account totals
- Added comprehensive translations for detailed view
- Navigation breadcrumbs and back buttons
- Professional styling with Dolibarr UI components
This provides complete transparency into which accounts contribute to each CA-3 line without touching the calculation logic.
Changed:
- Module family from 'other' to 'financial'
- Module will now appear in Financial category instead of Others
- More appropriate categorization for VAT declaration module
Changed:
- Removed top menu entry for DeclarationTVA
- Moved module link to Comptabilité (Accounting) left menu
- Changed mainmenu from 'declarationtva' to 'accountancy'
- Changed fk_menu to 'fk_mainmenu=accountancy'
- Module now appears under Accounting menu where it belongs
Fixed:
- Line 16 is calculated automatically, not configured
- Removed line 16 from CA-3 line definitions in config class
- Line 16 will still be calculated and displayed in the view
- Only user-configurable lines remain in the config
Fixed:
- Store original amounts in line_label with special format
- Parse original amounts in view page helper function
- Display original amounts in brackets: 124 (123.67)
- Handle both base and VAT amounts separately
- Original amounts now visible in amount columns
- Clear transparency for rounding decisions
Added:
- Round all VAT amounts to whole numbers using round() function
- Store original amounts in line_label with brackets [Original: X.XX]
- Round totals in updateDeclarationTotals() method
- Round amounts in createCA3Line() method
- This ensures VAT declarations only show whole numbers as required
- Original amounts are visible for transparency
Fixed:
- Line 25: Only shows value if net_vat_due < 0 (VAT credit - we receive money)
- Line TD: Only shows value if net_vat_due > 0 (VAT due - we pay money)
- Clear separation between payment (TD) and receipt (25) scenarios
- Line TD description: 'TVA due (montant à payer)'
- This clearly separates when we need to pay vs receive VAT
Fixed:
- Line 25: TVA brute due (Total VAT collected) - always positive
- Line TD: TVA due (absolute value) - never negative, shows abs(net_vat_due)
- Line TD appears between lines 26 and 28 in Section D
- Line TD shows 'TVA due (valeur absolue)' as description
- This ensures VAT due is never negative, even with VAT credits
Added:
- Line 23: Subtotal of lines 20, 21, 22 (for user reference)
- calculateLine23() method that sums VAT amounts from lines 20, 21, 22
- Line 23 display in Section C between lines 22 and Section D
- Line 23 shows as 'Sous-total TVA déductible (20 + 21 + 22)' with bold formatting
- Provides subtotal for Section C just like line 16 for Section B
Added:
- Line 16: Subtotal of lines 08, 09, 9B (for user reference)
- calculateLine16() method that sums VAT amounts from lines 08, 09, 9B
- Line 16 definition in CA-3 line definitions
- Line 16 will appear automatically in the view page
- This provides a subtotal for the user before line 17 (manual entry)
Fixed:
- Line 17 is for manual entry only (paper form)
- Removed line 17 from automatic totals calculation
- Only lines 08, 09, 9B contribute to total_vat_collected
- This should give the correct value for line 25
Fixed:
- Only sections B and C VAT amounts are summed for totals
- Section A lines (A1-A5) are excluded from totals calculation
- Only VAT amounts (not base amounts) are included in totals
- This should fix line 25 showing correct value (406.28)
Added:
- Debug logging for total VAT collected and deductible amounts
- This will help identify why line 25 shows wrong value (should be 406.28)
- Will show what values are being summed for the totals
Enhanced:
- D-section lines are now calculated automatically from other sections
- Line 25: TVA brute due (sum of sections A and B)
- Line 26: TVA déductible totale (sum of section C)
- Line 28: TVA nette due (25 - 26, if positive)
- Line 29: Crédit de TVA (26 - 25, if negative)
- Configuration page skips D-section as it's calculated
- Added explanatory note in configuration
- Result lines show 'Calculated from...' labels
Enhanced:
- Configuration form now shows separate fields for base and VAT accounts for lines 08, 09, 9B
- 'Comptes de base (ventes)' for sales accounts (7xxxx)
- 'Comptes de TVA' for VAT accounts (4457xx)
- Form processing handles both base_account_codes and vat_account_codes
- Calculation logic separates base and VAT amounts for these lines
- Base accounts contribute to base_amount, VAT accounts to vat_amount
- Account labels show (base) and (VAT) suffixes for clarity
Enhanced:
- Updated CA-3 line definitions for 08, 09, 9B to show both base and VAT
- Changed type from 'vat' to 'base_vat' for these fields
- Updated view table to show 5 columns: Line, Description, Base HT, VAT, Total
- Added language translations for new columns
- Fields 08, 09, 9B now display both base amounts and VAT amounts
- Enhanced debugging to show final amounts for each line
Fixed:
- When debit = credit (balanced account), use credit amount (VAT collected)
- When debit != credit (imbalanced), use absolute difference
- This handles the case where VAT accounts are balanced out
- Now shows 391.51 instead of 0.00 for field 08
Added:
- Log which CA-3 lines have mappings
- Log account codes being processed
- Log amounts found for each account
- Log when no mappings found for a line
- This will help identify why field 08 isn't working
Fixed:
- Process ALL CA-3 lines (A1-A5, 08, 09, 9B, 17, 20-22, 25-26, 28-29)
- Create records for all lines, even if no accounts mapped
- Show 'No accounts mapped' for lines without configuration
- Now all CA-3 lines will appear in the table with proper amounts
- Lines with mapped accounts will show calculated amounts
- Lines without mappings will show 0.00 but still be visible
Fixed:
- Use abs() for VAT account calculations
- VAT accounts typically have credit side amounts
- Now shows positive values: -1957.57 -> 1957.57
- Enhanced logging to show debit/credit breakdown
Fixed:
- Group account mappings by CA-3 line before processing
- Sum all accounts for the same CA-3 line (e.g. A1 = 7061330 + 7061320)
- Create single CA-3 line record with combined amounts
- Combined account labels for better visibility
- Now correctly calculates: A1 = 904.12 + 1053.45 = 1957.57
Fixed:
- Use correct table: llx_accounting_bookkeeping
- Use correct column: numero_compte (not account_number)
- Use correct date column: doc_date
- Removed unnecessary table discovery
- Queries now match actual Dolibarr database structure
Updated:
- Focus on accounting_line table (most likely to exist)
- Added comprehensive table discovery with column structure
- Check for accounting_account, accounting_journal, accounting_line
- Removed dependency on _bookkeeping tables
- Will discover actual table structure in your Dolibarr installation
Debug Features:
- Try multiple possible table names (accounting_bookkeeping, accounting_bookkeeping_tmp)

SQL Path Fix:
- Fixed module init() to look in /custom/declarationtva/sql/ instead of /declarationtva/sql/
- Updated dolibarr_allversions.sql with MVP schema content
- Ensures tables are created with correct structure from the start
Schema Updates:
- Uses MVP schema with correct unique constraints
