changed actions showing the same data in different reports

Summary:

I review the monthly audit change reports and find that the exact same data will appear in a gorup of reports

For example a change in Global human resources will appear in partner management, student records, trading community model etc.

This happens even when no business objects are switched on for auditing.

Content (please ensure you mask any confidential information):

I know that most of the records are 3rd party supplier set up or changes to users/employees.

But i would like to understand why i still receive output when no objects are set up for audit reports
