I recieved this query from Toomas at Symantec Support and it worked well. One drawback is that the results are not clickable and apperently this is not possible or really hard to accomplish.
Here's the working query (Thanks Toomas):
SELECT
rp.ReportProcessID AS [Ticket ID],
rp.ProcessName AS [Ticket Title],
rp.Result AS [Status],
rp.PercentComplete AS [Percent Complete],
rp.ProjectName AS [Project Name],
rp.ProcessStarted AS [Started],
t.WFTaskNumber AS [Task Number],
t.AssignedDate AS [Task Assigned Date]
FROM ReportProcess rp
LEFT JOIN Task t ON rp.SessionID=t.SessionID
LEFT JOIN TaskAssignment ta ON t.TaskID=ta.TaskID
WHERE ((rp.Result!='Closed') AND (PercentComplete!='100'))
AND (t.CanBeCompleted!=0 OR t.CanBeCompleted IS NULL)
AND ta.ReferenceID IS NULL
ORDER BY rp.ReportProcessID DESC
