When sales and purchase invoices are posted to the ledger, an audit trail is created that can be viewed. To select the period for which the information is displayed, use the Show option; to view only specific transaction types, use the Type drop down list. The display can also be customised.

You can click on a row and use the Amend button to change the transaction date and or the reference. If the selected row is part of a group of transactions then associated transactions are also updated.
