Part/Customer/Vendor Changes audit report

Has anyone developed a good report to show changes made to the part,
customer, and vendor files? For example, if a person changes a unit
price or cost on a part. Or, if a person changes the credit limit on
a customer.

I have the change log turned on for some of this, however... I need
something in report format that can be reviewed and signed off on (for
SOX requirements).
