Exclusive Field
For each assignment rule, the administrator can designate whether that rule is exclusive.
If a rule is exclusive and has assignees, then all assignees from other rules are discarded. If there are no exclusive rules, then the primary rule is the rule with the highest-scoring assignee and the primary assignee is the highest-scoring assignee. In this case, no assignees from the other rules are discarded; however, if the assignment object does not allow for more than one assignee, then only the primary assignee is assigned.
If there are multiple exclusive rules, then the exclusive rule with the highest-scoring assignee is chosen as the only exclusive rule. However, if multiple exclusive rules with equal scores qualify, then the default employee, default position, or default organization is assigned, because Assignment Manager is unable to determine the winning rule. For more information about assigning a default employee, default position, or default organization, see Assignment Methodology.
You make an assignment rule exclusive by checking the Exclusive flag for the assignment rule.
