}

Individual line item within a journal entry.

Each line represents a debit or credit posting to a specific GL account. Line items must be balanced within a journal entry (sum of debits = sum of credits).

Fields

document_id: Uuid

Parent document ID (matches header)

line_number: u32

Line item number within document (1-based)

gl_account: String

GL account number

account_code: String

Account code (alias for gl_account for compatibility)

account_description: Option<String>

Account description (for display)

debit_amount: Decimal

Debit amount in transaction currency (positive or zero)

credit_amount: Decimal

Credit amount in transaction currency (positive or zero)

local_amount: Decimal

Amount in local/company currency

group_amount: Option<Decimal>

Amount in group currency (for consolidation)

transaction_amount: Option<Decimal>

SOTA-4 Document/transaction-currency amount (SAP WRBTR) when the JE posts in a foreign currency. debit_amount/credit_amount/local_amount remain the company-ledger amount (SAP DMBTR — the ledger and trial balance aggregate these, unchanged), while this carries the original foreign value at header.currency / header.exchange_rate. None for company-currency JEs. Additive: ledger coherence is untouched.

cost_center: Option<String>

Cost center assignment

profit_center: Option<String>

Profit center assignment

business_unit: Option<String>

Business unit / division assignment. An organisational dimension that rolls up cost centers (a few BUs carry most postings, as in the corpus). #[serde(default)] so older JSON without the field still deserialises.

segment: Option<String>

Segment for segment reporting

functional_area: Option<String>

Functional area

line_text: Option<String>

Line item text/description

text: Option<String>

Text field (alias for line_text for compatibility)

reference: Option<String>

Reference field

value_date: Option<NaiveDate>

Value date (for interest calculations)

tax_code: Option<String>

Tax code

tax_amount: Option<Decimal>

Tax amount

assignment: Option<String>

Assignment field (for account assignment)

offsetting_account: Option<String>

Reference to offsetting account (for network generation)

is_suspense: bool

Is this posting to a suspense/clearing account

trading_partner: Option<String>

Trading partner company code (for intercompany)

quantity: Option<Decimal>

Quantity (for quantity-based postings)

unit_of_measure: Option<String>

Unit of measure

unit: Option<String>

Unit (alias for unit_of_measure for compatibility)

project_code: Option<String>

Project code

auxiliary_account_number: Option<String>

Auxiliary account number (FEC column 7: Numéro de compte auxiliaire) Populated for AP/AR lines under French GAAP with the business partner ID.

auxiliary_account_label: Option<String>

Auxiliary account label (FEC column 8: Libellé de compte auxiliaire) Populated for AP/AR lines under French GAAP with the business partner name.

lettrage: Option<String>

Lettrage code (FEC column 14: Lettrage) Links offset postings in a completed document chain (e.g. invoice ↔ payment).

lettrage_date: Option<NaiveDate>

Lettrage date (FEC column 15: Date de lettrage) Date when the matching was performed (typically the payment posting date).

transaction_id: Option<String>

Stable per-line transaction identifier.

Deterministically derived from (document_id, line_number) so it stays consistent across regenerations of the same dataset. Populated lazily at write time from JournalEntryLine::derive_transaction_id when not already set.

predecessor_line_id: Option<String>

v5.8.0 — predecessor line in a document booking chain.

Set to the transaction_id of the line in a prior journal entry that this line directly succeeds in a document chain (e.g. a payment line’s predecessor is the corresponding line in the vendor invoice JE; a goods-receipt line’s predecessor is the matching line in the purchase-order JE). None for purely-GL adjustments, period-close postings, payroll, or the root (first) document in a chain.

Used by the graphs/je_network.csv flat edge-list output to trace booking chains across JEs without joining against document_references.json.

Implementations

impl JournalEntryLine

pub fn debit( document_id: Uuid, line_number: u32, gl_account: String, amount: Decimal, ) -> Self

Create a new debit line item.

pub fn credit( document_id: Uuid, line_number: u32, gl_account: String, amount: Decimal, ) -> Self

Create a new credit line item.

pub fn is_debit(&self) -> bool

Check if this is a debit posting.

pub fn is_credit(&self) -> bool

Check if this is a credit posting.

pub fn signed_amount(&self) -> Decimal

Get the signed amount (positive for debit, negative for credit).

pub fn derive_transaction_id(document_id: Uuid, line_number: u32) -> String

Derive a stable per-line transaction id from (document_id, line_number).

Deterministic: the same input always returns the same id, so the value is stable across regenerations of the same dataset and across crate versions. Uses UUID v5 (SHA-1) under Uuid::NAMESPACE_OID.

pub fn ensure_transaction_id(&mut self)

Populate transaction_id from (document_id, line_number) if unset.

pub fn account_code(&self) -> &str

Get the account code (alias for gl_account).

pub fn account_description(&self) -> &str

Get the account description (currently returns empty string as not stored).
