Ledger Transactions Overview

A robust ledgering system needs a Transaction model to enable atomic movement of money among 2 or more Accounts and enforce double-entry rules.

Transactions allow you to specify groups of Entries that either must all succeed or all fail. The total balance of all Entries on a single Ledger Transaction must have equal debits and credits. In order to guarantee atomicity, all the non-discarded Entries on a Transaction must share the status of the Transaction. This ensures that all Entries progress in status at the same time, all-or-nothing.

A Ledger Transaction can have different transaction statuses. A posted Ledger Transaction is financially immutable and its Entries cannot be updated, though its metadata can be updated.
