Audience targeting is a page layout feature that allows admins to create different versions of a Lightning page for different audiences, such as user profiles, roles, or permissions. Audience targeting can be used to control the visibility of the entire page or specific components on the page, such as tabs, fields, or sections. Audience targeting can help create personalized and relevant experiences for different types of users, and reduce the need for multiple page layouts1.
Audience targeting is the most suitable feature for the UX Designer to use in this case, because it can help them customize the Order record page layout for internal and external users, without creating separate page layouts. For example, the UX Designer can use audience targeting to show or hide certain fields, sections, or tabs based on the user’s profile or permission set. This way, the UX Designer can ensure that each user sees only the information that is relevant and appropriate for them.
Field-level security is a feature that allows admins to restrict the access and editability of fields for different users, based on their profiles or permission sets. Field-level security can help protect sensitive or confidential data, and enforce data quality and integrity. However, field-level security does not affect the visibility of fields on the page layout, only the access and editability. Field-level security also does not apply to other components on the page, such as tabs or sections2.
Dynamic forms is a feature that allows admins to add, group, and reorder fields and sections on a Lightning page using the Lightning App Builder. Dynamic forms can help create flexible and dynamic page layouts that can adapt to different contexts and scenarios. Dynamic forms also support visibility rules, which can be used to show or hide fields or sections based on filters or conditions. However, dynamic forms are not available for all standard objects, and they do not support audience targeting. Dynamic forms also do not affect the visibility of other components on the page, such as tabs34.
