Thank you for reaching out to us through the Forum. You can view other user’s time sheet reports, if you have one of the following roles in the projects and organization:
Project managers can see time sheets of all resources working in your projects
Direct managers can view time sheets of their subordinates (Resources on Tasks they are Managing)
Super Users can see time sheets of all resources in the organization
Use the Change User filter to switch between users’ timesheets. Let me know if this information helps.
