Restrict Level One Lookup Using Scope Access Settings
From SmartWiki
When using Application Scope Access - the Lookup for selecting an external company can be restricted by selecting roles in the Roles to Restrict Level One Lookup Using Scope Access Settings. Under UTA Settings > Application Access Scope, there is a new section where you can select the roles to use to access scope settings for what to display in the lookup box for level one items. This only applies to the level one standard field lookup (ie. Company), UTA Contacts tab lookup, and UTA Companies tab lookup.
Impact: When enabled, a user that clicks the Lookup button will only see the companies that they are associated with in the Application Scope Access list where they are in the role that has been selected in the role box.
