Hi, 

We just created a check for a vendor and noticed that the check name was updated to a random person and the address had been changed to 'null' in all fields. I searched the audit log and found that the vendor appeared in our audit log, showing they made changes to their vendor account recently. 

How can they do this? 

How do we switch this feature off? 

How can we be alerted in future if this feature cannot be switched off? 

Thanks

Caroline
