Check Data, the audit log and the closing-date password

6 min · Intermediate

Three tools keep your books trustworthy. Check Data tests the whole file for problems and changes nothing (for bookkeeping mistakes such as a bill entered twice, use Books Checkup). The audit log records who did what and when. The closing date locks finished periods, and its password lets an administrator make a recorded exception.

In this lesson you will

  • Run Check Data and read the result
  • Find who changed what in the audit log
  • Set a closing-date password for locked periods

Before you start

Check Data result: your data is healthy, no problems found

Check Data

Step 1: Run the checks

Open Company → Check Data and click Verify data. It checks that every transaction balances, no journal lines are orphaned or point at a missing account, the trial balance ties out, the A/R and A/P control accounts match their aging reports, and no inventory has gone negative. It is read-only and changes nothing.

  1. Verify data runs the checks. Afterwards the button says Verify again.

Step 2: Read the result

A green line means the file is healthy. Problems are listed under Errors, and notes worth a look under Advisory, each with its category and a description. The line below the result shows how many transactions and accounts were checked, and when.

Check Data: your data is healthy, no problems found, 31 transactions across 35 accounts checked
Tip: Run Check Data before a backup you plan to keep, before a year-end close, and whenever AcboBooks warns that the books are out of balance.

The audit log

Step 3: See who did what

Open Company → Audit Log (Administrators only). The most recent 500 entries are listed newest first: When, User, Action and Detail. It records sign-ins and sign-outs, users added and passwords set, backups, file password changes, hosting starts and stops, and every change to the books.

  1. Export Excel / CSV saves the log for your accountant or your records.
  2. The columns: when, which user, what they did, and details.

Tip: For the same history over a date range, with friendly action names and a filter, use Reports → Audit Trail (see the Reports and year-end track).

The closing-date password

Step 4: Lock closed periods, with a recorded way in

In Company → Company Settings, the Close the Books panel sets a Closing date: transactions on or before it can no longer be added, edited, voided or deleted. Below it, Closing-date password lets an administrator still post into the closed period by entering the password, which unlocks it for 15 minutes. Every unlock, and every posting into the closed period, goes into the audit log, so the lock can be overridden but never silently.

  1. Closing date, then Set.
  2. New password (at least 4 characters), then Set password. Once set, the same box unlocks the period with Unlock for 15 minutes.
Close the Books panel with the closing date field and the closing-date password field
Tip: Choosing the closing date is part of the month-end and year-end routine; see the Reports and year-end track.

Questions

Check Data found errors. What now?

Read each message: it names the transaction or account involved. Fix that entry, or restore a recent backup made before the problem started, then run Check Data again. If you are stuck, use Help → Copy Diagnostics for Support and email us.

Can a user hide their changes from the audit log?

No. Entries are written by AcboBooks itself, and there is no screen to edit or delete them.
