Bug in `parseOBJEKT` — wrong dimension ID used when creating on-the-fly dimension** +- **Code:** `SieDocumentReader.java:584` — `sieDocument.getDIM().put(dimNumber, new SieDimension(number))` passes the *object* number (`number`) to the `SieDimension` constructor instead of `dimNumber`.

Writer emits `#DIM` records for all 19 default dimensions unconditionally** +- **Spec:** `#DIM` is **not permitted** (`-`) in Types 1 and 2. +- **Code:** `SieDocumentWriter.java:216-224` — `writeDIM()` iterates all `sieDoc.getDIM().values()` which always contains the 19 pre-populated default dimensions from `SieDocument`'s constructor. +- **Fix:** Either skip pre-populated ("default") dimensions (which have `isDefault=true`) or skip `writeDIM()` entirely for SIE types 1 and 2. + +--- + +**5. Writer `writePeriodValue` silently drops the quantity field** +- **Spec:** `#IB`, `#UB`, `#OIB`, `#OUB`, `#RES` all have an optional `kvantitet` field. +- **Code:** `SieDocumentWriter.java:233-247` — `writePeriodValue` builds the line with `yearNr`, `accountNr`, `objekt`, `amount` but never appends `v.getQuantity()`. Quantity data is lost on write. +- **Fix:** Append quantity when non-null and non-zero, same as `writePeriodSaldo` already does. + +--- + +**6. Writer does not emit `#BKOD`** +- **Code:** `SieDocumentWriter.writeContent()` — `SIE.BKOD` is never written. `SieCompany.sni` is parsed and stored but silently discarded on write. Round-trip is lossy. +- **Fix:** Add a `writeBKOD()` method, guarded by `sni > 0` and SIE type ≠ 4I. + +--- + +**7. `makeSieDate` returns `"00000000"` for null — written into `#GEN`** +- **Spec:** `#GEN datum` is a mandatory, valid YYYYMMDD date. +- **Code:** `SieDocumentWriter.java:408-413` — `makeSieDate(null)` returns `"00000000"`. This is used for `#GEN`'s date field (`getGEN()`, line 362) if `GEN_DATE` is null. `00000000` is not a valid date. +- **Fix:** Throw or log on null; or ensure `GEN_DATE` is set before writing. + +--- + +### MEDIUM — Missing Mandatory-Field Validation + +The `validateDocument()` method at `SieDocumentReader.java:776` checks only `#GEN` date, `#OMFATTN`, and `#KSUMMA`.

Amount max-2-decimal-places not enforced on read or write** +- **Spec:** "At most two decimal places (ören) are permitted." +- `BigDecimal` on read accepts any precision. `toPlainString()` on write may emit more than 2 decimal places if the stored value has them. + +**11. Account numbers not validated as numeric** +- **Spec:** "`kontonr` must be numeric." +- **Code:** `parseKONTO` stores whatever string it receives. + +**12. `#ORGNR` format not validated** +- **Spec:** Must contain a hyphen after the 6th digit (e.g. `556334-3689`). +- **Code:** `SieDocumentReader.java:351` — stored as-is. + +**13. Verification ordering not enforced** +- **Spec:** "Numbered verifications within a series must appear in ascending verification number order." +- **Code:** No ordering check in `closeVoucher`. + +**14. Trailing empty quoted string at end of line is dropped by `splitLine`** +- **Spec:** Empty quoted fields (`""`) are valid. +- **Code:** `SieDataItem.java:179` — the final `buffer.length() > 0` guard misses an empty string that was just closed (e.g. the trailing `""` in `#GEN 20080101 ""`). + +**15. CRC32 may include whitespace and quotes inside object lists** +- **Spec:** "Whitespace and tabs between fields — excluded; Enclosing quote characters — excluded; Braces — excluded." +- **Code:** `SieCRC32.addData()` strips `{` and `}` but the object list data (e.g. `1 "0123"`) retains internal whitespace and quotes because `splitLine` does not strip quotes when `isInObject == true`. The CRC feeds `1 "0123"` to the hash instead of the spec-compliant `10123`.

Writer fixes: ORGNR null guard, skip default/forbidden DIM records, append quantity in period values, add writeBKOD, GEN date null fallback, 2-decimal amount truncation. Reader soft validation warnings for mandatory fields, forbidden records, period format, account numbers, amount decimals, voucher ordering, and ORGNR format. CRC32 now strips quotes/spaces per spec. SIE5 opt-in strict validation for fiscal years, currency, journal entry ordering, quantity/amount sign, foreign currency sign, and balance completeness. Added getActiveLedgerEntries() convenience. 26 new tests (158 total, all passing).
