ArcGIS 10 has taken away Crystal Reports with no real improvements on the native reporting capabilities. If you can select from a number of layers at one time, then you should be able to report on all those layers with one report. This can be done with Crystal Reports (no longer available) but not with the native Arc-reporting.
We have a project where we need to create a report of everything (churches, populations, wetlands, bats, etc., all in different layers.) that occurs within a certain distance to a roadway. I can't figure out a way to do that with what is available in ArcGIS 10. Other people must need this feature.
