Once you delete a transaction, you cannot restore it. However, using the Audit Log, you can recover the details of the deleted transaction so you can re-enter it.

Here's how: 

1. Go to Settings.
2. Select Audit Log.
3. Click the dropdown menu▼, select the appropriate user, date changed, and event(s).
4. Locate the deleted transaction. (Tip: To easily find deleted transactions, use the browser search Ctrl + F and type "deleted").
5. Under the History column, click on View.

Note:

• Audit Log only works for transactions that were saved. There is no available report for deleted transactions. Consider voiding a transaction instead of deleting or completely removing it from your records.
