Users are complaining to you that the Milestones related list is not showing the most useful fields on the Project page. Which sequence of steps…

In the Salesforce platform, on which Certinia PSA is built, the display of a related list is controlled by the page layout of the parent object. In this scenario, the Project is the parent object, and the Milestone is the child object in a master-detail relationship. To change the fields (columns) shown in the Milestones related list, the administrator must edit the Project object's page layout, navigate to the Milestones related list section, and use the properties editor to add, remove, or reorder the fields.

B. The Milestone Page Layout controls the detail page for a single Milestone record, not the related list of Milestones that appears on the Project page.

C. Field Sets are used to control fields displayed on Visualforce pages or custom Lightning components, such as the Project Planner, not standard page layout related lists.

1. Salesforce Help Documentation: "Customize Related Lists". This document outlines the standard procedure: "From the management settings for the object you want to edit, go to Page Layouts... In the page layout editor, scroll down to a related list and then double-click it... Select the fields you want to display in the related list". This confirms the correct path is via the parent object's page layout.

2. Certinia PSA Administration Guide: Section: "Custom Fields and Layouts". The guide states, "You can add custom fields to PSA objects and add them to page layouts, field sets, and list views using standard Salesforce functionality." This directs administrators to use the standard platform method described in option A for page layout modifications.
