When you assign Create, Edit, Delete permission to a user group, members of the user group are able to perform several tasks in the folder. Assigning Create, Edit, Delete permission to a user group automatically assigns Run Component Procedures and Check In Current and Configure permission to the user group.
Create new subfolders
Subfolders inherit the permissions of the parent folder when the subfolders are created. These permissions can only be modified by the owner user group.
Create new plans, components, and folders within the current folder
Check in new versions of plans and components
Rename subfolders
Change a folder's description
Move plans, components, and folders
To move an object, you must have write permission on the parent folder and the destination folder.
Delete plans and components
Delete folders
To delete a folder, you must have write permission on the parent folder and all subfolders.
Perform all tasks allowed by Run Component Procedures and Check In Current permissions.
You need to be particularly careful about assigning Create, Edit, Deletepermission to a user group when that user group also has Allow on Host Set permission. Users in this type of user group will have free reign over a particular host set since they will be able to write plans and execute them as they choose.
