Varying financial account details by account type without record types
Key Takeaway
The standard Financial Account object doesn't support record types. Store the kind of account in its built-in Type picklist, and use Dynamic Forms with visibility filters on Type to give each kind of account its own fields on the record page.
On the standard Financial Account object, you can't use record types to give a checking account and a mortgage their own set of details. Three things do that job instead. The Type picklist holds the kind of account. Dynamic Forms break up the record details on the page. Related standard objects hold details such as balances, addresses and party roles.
Two ways to model financial accounts
Agentforce Financial Services can model financial accounts in two ways. You can use the objects in the Agentforce Financial Services managed package. You can also use standard objects such as Financial Account, Financial Account Party and Financial Account Balance.
The standard objects become available when you turn on the "Financial Account Management Standard Objects" setting. When the setting is on and the managed package is installed, both sets of objects are visible in the org.
Don't mix the two models. Use either the managed package objects or the standard objects consistently for the financial account and its related features.
