Hello Kyle,
many thanks. I only see, that OTR buffer was reset. After searching for some information in the SAP notes this is the "online text repository" buffer, and I'm not sure, if this is related to the work items. If I reset this buffer in AL12 I get the same entries in the syslog under my user id like in your screenshot. Do you know, when you have reported the issue to your basis team and when it was resolved? Could you please check the syslog for this time frame, if you see entries for a basis user, if they have called something? Some actions on the system like parameter switches at runtime or buffer reset are logged in the syslog. If you know the user ID, under which basis team works on the system, you can check also statistics in ST03 for this user, you should see, which transactions and reports they have called.
Regards,
Alwina
