New or modified profiles must be activated before they can be assigned to users or become effective in the system.
Activation copies the maintenance version of a profile to the active version. If the activated profile already exists in a user master record, the changes to it become effective as each affected user logs onto the system. Changes are not effective for users who are already logged on when the profile is activated.
To activate a profile, choose Profile → Activate on the Profile List screen. If an active version of the profile exists, you will see the active and maintenance versions of the profile so that you can verify the changes.
