When you modify an item on the Split/Skill Access page, you cannot change the user ID or the assigned splits/skills. You can only modify the access permissions.

From the Current ACD list, select the active ACD for which you want to manage split/skill access.
CMS Supervisor displays the existing split/skill and exception access permissions for the selected ACD.
Click next to the item you want to modify.
The Modify Item window is displayed.
Select or clear the Read, Write, and Exceptions check boxes as required.
