I have a weird question. Just got a ticket saying a JE was made in error 2 weeks ago and the employee said it must have happened when they were entering in a TAX ID number for a Vendor. The JE line total equals the tax ID number. The user doesn't remember creating a JE and it is a UI creation according to the system notes. I am trying to figure out how this might have happened. My best guess is they had a separate window opened and thought they were typing into the EIN field, when in reality they were typing into the JE amount field. They then saw that it wasn't populated and re entered it correctly in the Vendor record.

the changes in Vendor record no way can effect a transaction, it is impossible. Seems like your assumption is correct or may be the user was drunk or high weed

Can't UI also mean that a client script made the change?
