Thanks again. I don't have Jaspersoft Studio installed. I'm on v14.3 currently (we're in the process of exploring the upgrade to v15.x). A while back I inquired with CA Support about Jaspersoft Studio, and was provided a similar document, and was instructed to contact the Services team for assistance beyond that, which deterred me from exploring it further.
For the most part, I've been able to get Ad Hoc to work for me, but I hit a wall with the current report I'm working on (looking to only return the most recent Status Report details). I reviewed the documentation you linked, but it doesn't cover that (or at least, I'm not finding anything), hence my query to the community. If I could hack the SQL code, I could set that up, but that doesn't appear to be an option in Ad Hoc, so I'm hoping there's a way to do that in Ad Hoc, else I'll be making a portlet...
