Typical training that ADP delivers is basically "Train your employees to confusion". They say ReportSmith is really easy to use, but they only show you the really basic stuff. That's why ADP bills 1000 per day to come out and build reports for companies (which they don't do a good job in doing).
And I have to admit, I'm glad that there isn't really much in the way of training and/or education in regards to ReportSmith because I can now bill 120 an hour to my clients since very few people really know how to build reports in ReportSmith correctly.
The only real way to learn the product is to go to the SRS website and download their documentation. Most importantly, take a good look at ReportBasic and the Macros section.
