The appropriate configuration point is the Role field on the Financial Account Role object. Financial Account Role represents the relationship between a financial account and a person, contact, or account. Examples include primary owner, joint owner, beneficiary, trustee, or another organization-specific participation role.
Salesforce ' s Financial Services data model represents these relationships through the Financial Account Role structure. Current standard data-model mapping carries the same concept into Financial Account Party, where the managed-package Role field maps directly to the standard Role picklist. This confirms that role classification belongs on the relationship record rather than on the Financial Account itself.
A Joint Owner or Primary Owner relationship should therefore not be modeled by creating new values or fields directly on Financial Account. The relationship object is specifically designed to support multiple parties and multiple relationship types for the same financial account. Account-Account Relationship addresses relationships between accounts or business entities and is unrelated to financial-account ownership or participation.
Accordingly, when additional customer-to-financial-account relationship categories are required, administrators should extend the Role picklist on Financial Account Role. This preserves the Financial Services relationship model and supports consistent ownership, reporting, rollups, and financial-account relationship processing.
