Two Salesforce recommendations for setting up partner roles in large orgs are B and C. Partner roles are roles that are assigned to partner users who access your Experience Cloud site through a partner account. A partner account is an account that has the Is Partner checkbox enabled. To set up partner roles, you should create them in a separate branch in your Role Hierarchy, which allows you to isolate partner data from internal data and control partner visibility and access. You should also grant partner users access to the partner account using a Sharing Rule, which allows you to share records owned by internal users with partner users based on criteria that you define.

The reason for this issue is that the Record Detail component populates the recordID associated with the object for the page template, so this component will not work for this use case. The Record Detail component is a component that displays the fields and values of a record on your Experience Cloud site. The recordID is a unique identifier that specifies which record to display. The Record Detail component uses the recordID associated with the object for the page template, which means that it can only display one record per object per page. For example, if you have a page template for Account, you can only display one Account record on that page using the Record Detail component. To display multiple records of different objects on a page, you need to use other components, such as Related List or Record List.

A prerequisite for creating a user that has a Partner Community license is to enable the account as a partner account. To do this, you need to have the ''Enable as Partner'' action on the Account page layout. This will allow you to convert an existing account or create a new account as a partner account.

Sharing rules allow you to extend sharing access to users in public groups, roles, or territories. You can use sharing rules to share records owned by realtors at DR with social workers at NMH, based on criteria such as record type, field value, or ownership.

Partner lead routing allows UMS to assign leads to partners based on predefined criteria, such as location, product, or industry. This helps UMS distribute leads more efficiently and increase partner engagement. Automated quoting capabilities allow partners to generate quotes for customers using UMS's pricing and discount rules. This helps partners close deals faster and more accurately.
