Explanation
Predefined reciprocal roles are available only in English and Referral record type labels are supported only in English are two language-related limitations of Financial Services Cloud. Predefined reciprocal roles are the roles that define the relationship between two individual clients or between an individual client and a group.
For example, Spouse, Child, Parent, etc. These roles are not translated into other languages and cannot be edited or deleted. Referral record type labels are the labels that indicate the type of referral, such as Client Referral or Prospect Referral. These labels are also not translated into other languages and cannot be edited or deleted. References: [Predefined Reciprocal Roles], [Referral Record Type Labels]

The following referral metrics are tracked with custom components included in Financial Services Cloud:
Expressed interests: This metric shows the number of referrals that have a specific expressed interest, such as a mortgage, a credit card, or a checking account. You can use this metric to understand the customer needs and interests that generate the most referrals.
My Top Referrers: This metric shows the top referrers who have created referrals for you, ranked by the number of referrals and the conversion rate. You can use this metric to identify and appreciate your best sources of business.
Referrals Assigned to me: This metric shows the number of referrals that are assigned to you and their status, such as New, In Progress, or Closed. You can use this metric to monitor and manage your referral pipeline and prioritize your follow-up actions.
