The follow article came from this link: https://community.intuit.com/questions/1128440-who-is-the-system-administrator-that-shows-up-in-the-audit-log
“Hello <name>! The System Administrator is our engineers working hard to improve our QBO product. Rest assured, we are not changing your data or anything in your company. Those edits you are seeing done by System Administration are merely our product code being updated internally. When we update that code it pushes it out to your company so that you can reap all the benefits of the new features when we release them.
You can always find update information on our bog at http://quickbooks.intuit.com/blog/. It’s a great idea to make it one of your Favorites. Thank you for reaching out to the Community Team for support.”
Basically, this means that, while the QBO developers are working on the Quickbooks Online software, you cannot sync Workshop Software with Quickbooks. This is not an issue. It just means that you will need to try the sync again in a couple of hours.
