You can run an Audit Trail report, @user010101. 

Follow the steps below on how to generate it:

1. Go to Reports menu and select Accountant and Taxes.
2. Choose Audit Trail.

The Num column will display the user-specified number for each modified or deleted transaction. The State column identifies whether you are looking at the most recent version of a transaction (the Latest) or an earlier version of the same transaction (a Prior).

When a transaction is added, one entry is listed directly under the transaction heading in the Audit Trail report. When a transaction is modified or deleted, the change displays directly under the transaction heading.

If a transaction is modified more than once, a Prior entry for each change displays under the same transaction heading. You can double-click on the transaction to view the added information.

I'm always glad to help if there's anything that you can help. Have a wonderful day!

I find it difficult to believe that I have to build a report containing every single transaction just to see who put an item on backorder.
