# Changelog
|
||||
|
||||
## 2025-10-28 - 1.2.1 - fix(skr.classes.account)
|
||||
Remove incorrect SKR04 automatic account 3300; improve VAT posting validation and test isolation; update readme hints and CI settings
|
||||
|
||||
- ts/skr.classes.account.ts: Removed account '3300' from the SKR04 automatic accounts list (3300 is Fahrzeugkosten and must be postable).
|
||||
- ts/skr.postingkeys.ts: Relax VAT amount requirement — VAT amount is no longer required when posting to VAT accounts or to debtor/creditor accounts (settlement lines).
|
||||
- ts/skr.classes.journalentry.ts: Detect VAT lines in journal entries and pass VAT-aware context into posting key validation to avoid false-positive VAT errors.
|
||||
- test/test.skr04.ts: Use timestamped database names to ensure isolated test runs and avoid DB conflicts during CI.
|
||||
- readme.hints.md: Updated status and notes (tests passing, recent fixes, architecture notes and validation pipeline).
|
||||
- .claude/settings.local.json: Added local CI/agent permission settings used by the project environment.
|
||||
|
||||
All notable changes to this project will be documented in this file.
|
||||
|
||||
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),

# Project Readme Hints
|
||||
|
||||
This is the initial readme hints file.
|
||||
## Current Status (2025-10-27)
|
||||
|
||||
### Test Results
|
||||
✅ **ALL 65/65 TESTS PASSING** (100%)
|
||||
|
||||
### Recent Fixes
|
||||
|
||||
#### Fixed: SKR04 Bug (Account 3300 Misclassification)
|
||||
**Problem**: Account 3300 was incorrectly hardcoded as an automatic account for SKR04
|
||||
**Root Cause**: Bug in `ts/skr.classes.account.ts:192` - account 3300 is "Fahrzeugkosten" (vehicle costs), NOT an automatic account
|
||||
**Solution**:
|
||||
1. Removed 3300 from automatic accounts list in `isAutomaticAccount()` method
|
||||
2. Updated test.skr04.ts to use timestamped database names to avoid conflicts
|
||||
**Files Changed**:
|
||||
- `ts/skr.classes.account.ts` - Fixed automatic account detection
|
||||
- `test/test.skr04.ts` - Added timestamp to database name
|
||||
|
||||
**Result**: ✅ All SKR04 tests now passing (jahresabschluss.skr04 + basic SKR04 tests)
|
||||
|
||||
### Architecture Notes
|
||||
|
||||
#### VAT Validation Logic (Recent Changes)
|
||||
- **skr.classes.journalentry.ts:224-273**: Detects VAT lines in entries to enable smart validation
|
||||
- **skr.postingkeys.ts:87-100**: Exempts VAT accounts and debtor/creditor accounts from VAT amount requirements
|
||||
- **Rationale**: VAT accounts ARE the VAT; settlement transactions don't need VAT details again
|
||||
|
||||
#### Posting Key Usage Pattern
|
||||
- **Tax-free operations** (key 40): Internal adjustments, depreciation, closing entries
|
||||
- **VAT operations** (keys 3, 8, 9, 19, 94): Customer/supplier transactions
|
||||
- **Best practice**: Use posting key 40 for non-VAT lines in mixed entries
|
||||
|
||||
#### Account Structure
|
||||
- **Automatic accounts**: Cannot be posted to directly (1400 Debtors, 1600 Creditors, 3300 Bank)
|
||||
- **Personal accounts**: Created in ranges 10000-69999 (debtors), 70000-99999 (creditors)
|
||||
- **System enforces**: Must use personal variants instead of automatic accounts
|
||||
|
||||
### Validation Pipeline
|
||||
1. **Line-level**: Posting key required, account exists, VAT rules
|
||||
2. **Posting key level**: VAT amount requirements (with exemptions)
|
||||
3. **Consistency level**: No mixing tax-free and taxed (unless intentional)
|
||||
4. **Balance level**: Debits must equal credits (0.01 tolerance)
|
||||
|
||||
### Test Coverage
|
||||
- 65 test cases covering full accounting cycle
|
||||
- Complete Jahresabschluss (annual closing) workflow in SKR03
|
||||
- Report generation (Trial Balance, Income Statement, Balance Sheet)
|
||||
- Transaction reversal and audit trails
|
||||
- DATEV posting key validation
|
||||
|
||||
### Dependencies
|
||||
- MongoDB via @push.rocks/smartdata for persistence
|
||||
- TypeScript 5.8.3 with strict mode
|
||||
- @git.zone/tstest for testing framework

Zeitraum: ${this.options.dateFrom.toISOString()} bis ${this.options.dateTo.toISOString()}
|
||||
|
||||
STRUKTUR DES ARCHIVS
|
||||
--------------------
|
||||

- /data/metadata/signatures/: Digitale Signaturen und Zeitstempel
|
||||
|
||||
INTEGRITÄTSSICHERUNG
|
||||
--------------------
|
||||
- Alle Dateien sind mit SHA-256 gehasht (siehe manifest-sha256.txt)

|
||||
REIMPORT
|
||||
--------
|
||||
Das Archiv kann mit der SKR-Software vollständig reimportiert werden.
|
||||
Die Datenintegrität wird beim Import automatisch verifiziert.
|
||||
|
||||
COMPLIANCE
|
||||
----------
|
||||
- GoBD-konform
|
||||
- E-Bilanz-fähig (XBRL)
