Knowledge Management

Question:
I assigned a user to two different roles in 4.6c. Upon logon user has the both menus for the two roles. How can I assing her the profiles for the second role without her inheriting the menu as well.
I tried to assign the profiles of the second role to her directly without assigning her to the role through su01 but the system would not let me do it.

Answer:
You can put in one of the roles authority objects directly, from authorizations. User can do all that thing withouth seeing in her/his menu
