Setting Role Permissions
Minimum SharePoint site permissions: Site Collection Administrator
Each role works best if the user in these roles also have minimum permissions in SharePoint(SP):
| Role | SP Permissions | Location |
|---|---|---|
| Administrators | Contribute | Site Collection |
| Profile Editors | Contribute | CT Profile Import & CT User Profile Lists |
| Report Editors | Contribute | CT Config List: Target items () |
| Report Readers | Read | Site Collection |
You do not need to break inheritance on list items or lists as long as you don’t mind the user having Contribute access across the site collection.
Breaking Inheritance on list
To update the permissions on a CT List to allow targeted contribute or read access. Open Site Settings > Site Contents > CT List Name > Settings (3 dots) > Permission for this list. Click Stop inheriting permissions. Then add the user(s) to the list.
Breaking Inheritance on list item
To update the permissions on a CT List item to allow targeted contribute or read access.
Open target list > tick list item > make sure the 
icon is selected on the right of the page > select Manage access under Has access.
From there select the + sign next to Direct access > add user name and check access level by selecting the pencil on the right. Then Grant access.
If notify was left ticked the user will be notified that you have granted them access.
