Hi  @AnandVenkat ;

Access to Management (read, admin, etc.) is reserved for users that have access to one or all of the following categories:

- Admin rights on at least one workflow (Workflow Server > Workflows and then choose a workflow)
OR
- A member of the Security Administrators role (Users > Roles)
OR
- Admin rights on the Workflow Server (Workflow Server > Workflows > Server Rights)

In addition, reporting the Process Overview Report is available in Workspace if they do not wish to grant this level of permissions to a particular user.

Hope it helps.

-Regards;

Widson.
