Hi Tara,
You are on the right report for modifications. On the report it should show additions, modifications & cancelations. Attached is a screen shot of a test flight I just changed. The lower two lines are the addition of the flight, and the upper two lines are the modification. The report isn't perfect as it won't tell you what has been modified, just that the flights have changed from the last update. You can see you can also filter to only show modifications as well. Are you looking for more information on the modifications?
If you are not getting any modifications on the report, it is likely that the integration isn't completely correct. My guess would be that it is deleting out flights and re-entering them, rather than simply updating them. Are you using an automatic queue from concur/GDS to push changes back into cvent? That always helps.
