I don't want the member of these group to have write permission to other workareas.
No, I am trying to allow only a group of users to have read and write accessto only a certain subfolder of a workarea of a branch. In other words, I don't want the member of these group to have write permission to other workareas.
It's usually a good practice add your environment details to your signature. That way everyone won't ask you which systems, what versions, etc.So first off, What version of TeamSite are you using? OS?Your statements are confusing... other workareas or other subfolders?
