SAP KM default permission menu customization

Hi All,

I have created a Km Folder and want to give access to few users with the read privilege. I am adding the users using the permissions option in the

folder details .When i am adding the user, the default permission is "Full Control" which i have to manually change to "Read" .

My requirement is that the default should be "Read".

Please reply soon.

Regards,

Nitesh
