Have you ever had the location change on an invoice without knowing who did it or when?
You can check when the Location changed by clicking on the Status button on Pending List. It gives you a Date & Time Stamp.
If you really want to know who it is, there is a canned report that tracks the Locations and the person who is logged in when they are changed. Just send me an email and I will send it to you.
Or you could use the Downloader browse function if you don’t feel like running a report.
