A posting template: an ordered list of posting specs that a policy resolves into concrete postings.

Each spec references a symbolic account role, a direction (:debit or :credit), and the amount/currency variables (always :event_amount and :event_currency in v0.1.0). The journal builder resolves the role to a concrete account code via the knowledge layer's account_role facts.

Fields

• policy — atom() — the policy this template belongs to (e.g. :cash_deposit)
• postings — [posting_spec()] — ordered posting specifications

Posting spec

Each spec is a map with:

• :sequence — non_neg_integer() — ordering within the journal

• :direction — :debit | :credit

• :role — atom() — symbolic account role (e.g. :cash_account)
• :amount_var — :event_amount — always :event_amount in v0.1.0
• :currency_var — :event_currency — always :event_currency in v0.1.0

Example

%Logistiki.Accounting.AccountingTemplate{
  policy: :cash_deposit,
  postings: [
    %{sequence: 1, direction: :debit, role: :cash_account, amount_var: :event_amount, currency_var: :event_currency},
    %{sequence: 2, direction: :credit, role: :client_liability_account, amount_var: :event_amount, currency_var: :event_currency}
  ]
}
