RE: Adding SNOTE to Crystal Reports
Scott, I just modified that report to add the notes from the ARTran table and it worked just fine. I was able to add the note text field to the detail section and save the revised report in the usrrpt folder. When I launched the menu item, the Print Notes field showed and was enabled. So, the process as described works (not that it resolved your issue but, at least, you now know it should work).
What version of SL were you trying this on? I did my test on SL 2011 (just because that is what I had on that test computer).
