  • I concur with Stuart, no need for "reports" per say but I would use tables if they where more powerful.  Perhaps a report could be made that isn't linked to item types or other data just user input?  This may very well be possible already I haven't had time to look at reports with any real effort in a long time.  I distaste linking tables to excel because it's too easy to break them and end up with major issue that needs to be resolved at the worst of times.  Ideally deliverables need to be stand alone and robust enough to limit that kind of failure.
