User Change Record not getting populated

Hi all,

Iam using classes to assign notification to revision (cl_revision_wps->notification_assign) . After assignment the user chnge record (ie which user altered the notification and time) is not getting populated. In my initial analysis I found that the function modules are updating the change record ,the problem is only with the classes . Is this a known problem?

Guide me on how to proceed.
