Northern Trail Outfitters has a Customer Community for viewing discussions and Knowledge articles. The Customer Support team needs to add custom…

The most efficient and standard method to control field visibility in Salesforce is through Field-Level Security (FLS). By modifying the profile assigned to community customers, the administrator can revoke read access to the new custom fields on the Knowledge object. This declarative approach ensures the fields are hidden from customers wherever they access the article, without requiring custom code (Visualforce/Lightning Components) or inefficient content duplication. This is the most scalable, maintainable, and secure solution, aligning with Salesforce best practices.

A. Create separate articles without these custom fields for the Customer channel and include in the Community: This is highly inefficient as it creates redundant content, doubling the effort for content creation and maintenance.
C. Override the article detail page with a custom Visualforce page and hide these custom fields for customers: This is a code-based solution that is unnecessarily complex and less efficient than using the standard FLS feature for a simple visibility requirement.
D. Modify the article detail page with custom Lightning Components that hide these custom fields for customers: Similar to Visualforce, this requires custom development, which is more time-consuming and harder to maintain than the declarative FLS option.

1. Salesforce Help

"Control Access to Articles with Field-Level Security": This document explicitly states

"You can make a field on an article type visible

read-only

or hidden... Field-level security settings override page layouts and templates." This confirms FLS is the correct mechanism for hiding specific Knowledge fields from certain users.

2. Salesforce Help

"Field-Level Security": This guide provides the foundational concept: "Field-level security—or field permissions—control whether a user can see

edit

and delete the value for a particular field on an object." This applies directly to hiding the custom fields from the customer profile.

3. Salesforce Help

"Set Field-Level Security for a Field on All Profiles": This page details the administrative steps. An admin would navigate to the Knowledge object's fields

select the custom field

and adjust its visibility for the specific customer profile(s) used by the community

making it the most direct and efficient administrative action.
