How do you manage reporting in OTBI for courses with reassignment rules?

Summary:

What is the best way to report on compliance courses with reassignment rules so that you can filter down to a report which only shows the lastest record for each employee?

Content (required):

1) We have enrolled all employees, so we want to see people who haven't yet completed the course. To do this, I've set up to report at course level, so we can see the No Offering Selected Status

2) However, we don't want to see the future dated assignment for those staff who have completed or are in progress. I have therefore added a filter onto the Assigned On Date field, to exlude records that are after the current date.
