Explanation
There are two possible reasons why users are unable to access a report based on a custom report type created by an administrator. One is that the custom report type is in development mode, which means that it is not deployed and available for use by other users except for administrators and users with manage custom report types permission. The other is that the report is saved in a private folder, which means that it is visible only to its owner and not shared with other users or groups. References:

Explanation
Permissions and tab visibility are two options that administrators can adjust to fully restrict access to records for certain users or profiles. Permissions determine what users can do with records, such as create, read, edit, delete, view all, or modify all. Tab visibility determines whether users can see a specific object tab in their app launcher or navigation bar. By setting permissions and tab visibility to none or hidden for deal records for service users or profiles, administrators can prevent them from accessingdeal records via search or other methods.

Explanation
Flow Builder and Process Builder are two automation tools that should be used to accomplish this request.
Flow Builder can be used to create a flow that defines the logic and actions for creating a renewal opportunity, such as setting the stage, close date, and amount. Process Builder can be used to create a process that triggers the flow when an opportunity is closed won. References:
