How to Change Process View PermissionsCustom groups may not have the correct permissions to use commands in the process view of a ServiceDesk ticket, such as Work Task Assigned to Others. A minor customization of the SD.IncidentManagement project is needed to accomplish this.
Note: The minimum rights a user needs to have "Can Administer" rights for a process view for a ticket is being at least the Service Managers default out of box groups. This can be a workaround if a user is needed to have these rights, but not full administrative rights, if a custom group is determined to not be needed.
