sap b1 authorization change log display wrong updated user

hi,All

    I guesss someone of you has the problem of change log display wrong update users name (it's exist both sap b1 8.82 and 9.0 version),it would display common user name in authorization change log.in fact only super user could change the user authorization.

we had the same issue when we do internal audit .who knows what happend ? thanks
