Hi MD,
If you have made any changes to the product and classification in WSUS, you can check the
change.log (on the WSUS server, usually located in Program Files\Update Services\LogFiles).
As far as I know, in SCCM, you can consider viewing the WCM.log (on the site server, usually located in Program Files\Microsoft Configuration Manager\Logs) and also record the relevant changes.
Hope the above can help you.
Regards,
Yic
