thank you for your reply and the links, I've seen them before.
so if I get it right, i have to set the permission to every wiki page in the object permission of this site?
this is not so useful, is there an easier way?
what i don't understand is, how can i create a wiki page with native permission that only the SAP group see this site....
in the attachment are the 2 groups that i setup and thats the object permission view.
