This field displays the contacts from: - All accounts in the account relationship - All accounts in the account hierarchy - All accounts, if the **sn\_customerservice.contact\_relationship.restrict\_within\_account\_hierarchy** system property is set to **false**. However, when the **sn\_customerservice.contact\_relationship.restrict\_within\_account\_hierarchy** system property is set to **true**, only the contacts within the account hierarchy and account relationship are displayed. **Note:** By default, the **sn\_customerservice.contact\_relationship.restrict\_within\_account\_hierarchy** system property is set to **true**. If you're a customer service manager \(sn\_customerservice\_manager\), CRM foundation admin \(sn\_crm\_foundation\_admin\), CRM foundation data manager \(sn\_crm\_foundation\_data\_manager\), or an Account relationship data manager \(sn\_crm\_account\_relationship\_data\_manager\), you can create, update, delete, and view the list of contact relationships for an account. If you're a customer service manager \(sn\_customerservice\_manager\), customer service agent \(sn\_customerservice\_agent\), CRM foundation data viewer, \(sn\_crm\_account\_relationship\_viewer\), or and Account relationship viewer \(sn\_crm\_foundation\_data\_viewer\), you can view a list of the contact relationships for an account. When you select a responsibility for the contact, the responsibilities that are available are those responsibility definitions that are created with a type of **Contact**. **Note:** A contact can only be assigned with one responsibility per account. ## Configuring multiple contact relationships per account for a contact Before the Vancouver release, configuring multiple contact relationships for a contact with an account wasn’t enabled. The database-level unique index `company_contact` can be turned off only by the administrators. Starting with the Vancouver release, the Customer Service Management \(CSM\) application replaced the unique index and introduced the **Prevent duplicate for account-contact** business rule. This business rule enables administrators to disable the restriction of a unique index combination in the contact relationship by setting the **Active** flag to **False**. As a result, an administrator can assign multiple responsibilities per account for a contact.
