Which of the following can a viewer role not do?

In the context of a viewer role within the Profitability and Cost Management Cloud (PCMCS), the viewer role is primarily designed to allow users to observe and analyze data without having the capacity to modify it. This role typically includes permissions to interact with reports, access documentation, and even monitor performance metrics as these functions are crucial for stakeholders who need insights into the system performance and outputs.

Editing user roles, however, falls outside the scopes granted to a viewer role. Managing user permissions is a function that requires administrative capabilities to ensure system security and proper governance. This activity is restricted to individuals with higher privilege roles, such as administrators or managers, who can make significant changes to the configuration of the system and user access rights. As such, only those with the appropriate roles can edit user capabilities, reinforcing the structured access control necessary in enterprise applications.
