What it is
The audit trail is what lets you answer an information request without rebuilding anything: from a balance to the póliza (the Mexican term for a journal entry), from the póliza to the day's signed sheet, and from the sheet to the transaction, with its time and its user. In Containn it isn't assembled at month-end: it's written as things happen.
What gets recorded
| Event | What is kept | Where you see it |
|---|---|---|
| Signing the day | Frozen totals, who signed and when | Finances → Day close, Signed days table, and the DÍA CERRADO (day closed) stamp on Night Audit Totals |
| Reopening the day | Who, when, the required reason and how many times it has been reopened | Signed days, and Settings → Activity Log with the Finanzas (finance) filter |
| Póliza | Monthly sequence number, the hotel concept code on each line, and that date's CFDI (Mexico's electronic tax invoices) | Containn → Pólizas |
| Canceled póliza | Never deleted: it keeps its number, is marked Cancelada with the reason in its description, and stops counting in balances | Containn → Pólizas |
| Month-end close | Who closed it and when | Containn → Cierre de mes (month-end close) |
| Reopening a month or fiscal year | Who, when and the required reason; reopening the fiscal year cancels its closing póliza | Kept with the period |
| Changes to a reservation's charges and payments | Who, when, before and after | The reservation's Auditoría (audit) tab, and Settings → Activity Log |
| Daily transaction | Time, room, folio, concept, base, tax, service charge, total, user and revenue center | Finances → Movement journal |
Step by step: following a peso
- In Containn → Balanza de comprobación (trial balance), click the account: its subsidiary ledger shows each transaction with its date, póliza number and description.
- In Containn → Pólizas, pick the month and open the póliza: each line shows which hotel concept created it.
- If it's a daily póliza, find the day in Finances → Day close → Signed days: who signed it, with what totals, and whether it was reopened. See reports opens the sheet exactly as it was signed. The table shows the last 30 signed days; for an earlier one, open the Night Audit Totals report for that date.
- In Finances → Movement journal, pick that business date: there you'll find every transaction, with its time and its user.
The User column
The journal never says “not recorded”. If a person made the transaction, it shows their name; if the name was taken from the cash register close, it says so underneath. If it wasn't a person, it says what generated it: the night audit, an online payment, a sales channel prepayment, a data migration or the deposit ledger transfer. If the data is missing, it tells the cases apart: “Sin usuario · registro histórico” (no user, historical record) for entries made before the user was stored, and “Sin usuario · por revisar” (no user, to review) for entries that should have it. It never fills in a guessed name.
The month-end close screen shows who closed the month and when; the reason for reopening a month is kept with the period, but that screen doesn't show it yet. Day closes and reopenings, on the other hand, are also in Settings → Activity Log.
