A Platform Administrator wants to limit the kinds of reports their users can create. Which tool should the administrator use?

To limit the kinds of reports users can create, a Platform Administrator should use the "Hide Report Types" functionality. This administrative tool allows the administrator to control which report types are visible to users when they initiate the report creation process. By hiding specific report types from user profiles or permission sets, the administrator effectively prevents those users from building new reports based on those underlying data structures. This directly addresses the requirement of limiting the types of reports that can be created, without affecting existing reports.

B. Report Folder Sharing: This controls access permissions (view, edit, manage) for folders containing existing, saved reports. It does not prevent users from creating new reports of any type.

C. Standard Report Types: This refers to the predefined report types included with the platform. It is a category of report types, not an administrative tool for restricting their use.

D. Joined Report: This is a specific report format that combines multiple report blocks. It is a feature for data analysis, not a tool for controlling report creation access.

1. Salesforce Help, "Hide Report Types": "You can hide report types from the Create Report page. Hiding a report type doesn't delete it or any reports based on it. Instead, it removes the report type from view in the report type selection page so users can't create new reports with it." This document explicitly describes the function of hiding report types to control creation.

2. Salesforce Help, "Standard Report Types": This document lists and describes the out-of-the-box report types, establishing it as a category of features rather than a control mechanism.

3. Salesforce Help, "Share a Report or Dashboard Folder": This guide details how to set access levels for folders, confirming that folder sharing is about controlling access to saved reports, not limiting the creation of new ones. Section: "Folder Sharing in Lightning Experience".
