The ppsresource role is specifically designed to designate a user as a resource within the ServiceNow Strategic Portfolio Management (SPM) application. When a user is assigned this role, they become available for resource management activities. This means they can be included in resource plans, have their capacity and availability tracked, and be allocated to demands, projects, and other operational work. Without this specific role, a user will not appear in the lists of available resources for planning and allocation by resource or project managers.

A. itprojectuser: This role provides read-only access to project-related information. It does not designate the user as a plannable resource.

B. ituser: This is a generic, foundational role for IT users and is not specific to resource management or the SPM suite.

C. itppsuser: This role grants general access to the Project Portfolio Suite (PPS) applications but does not specifically mark the user as a resource for planning purposes.

In the table describing roles, the ppsresource role is defined as: "Users who can be requested as a resource on a resource plan. Any user with this role is considered a resource." This document also clarifies that itppsuser is for general access and itprojectuser is for viewing project information. (ServiceNow Vancouver Release Documentation, Strategic Portfolio Management, "Roles in Strategic Portfolio Management" section).
