With the Mass Changes function (transaction SU10), you can perform most of the changes that you can make for individual users in user maintenance for user groups; that is certain sets of users. This applies for Logon data, Defaults, Parameters, Roles, and Profiles.

The mass change functions apply to all of the users displayed in the initial screen unless you make a selection.


You must choose Change in the Address, Logon data and Constants tab pages for each change. In this way, you can ensure that your changes, such as the deletion of a field’s contents are accepted for the corresponding fields.
