This is another one driving me nuts!   I want to create a report showing the average size of full tapes for each backup server; however there does not appear to be a way of getting the report to produce an average for each backup server.  I start with the Media Details source and apply the Average operator but this results in a table which has server, volume name, size of volume (an average appears to be taken for all times that the volume details are recorded).  I have tried dropping the volume name and applying the Average function but no good.  Is there any way I can do this without having to import the results into Excel and produce the results there (very easily too).
