I usually take the defaults when installing stuff (especially in this case when I don't know much about SQL) so not sure why my test SQL server has SSAS whereas the one prepped by someone else (who said he also took the defaults) doesn't have it. Some posts on the Internet say that SSAS is installed if "Analysis Services" is listed in SQL Management Studio although both servers show this object with our production one not even listing SSAS under services.msc.
Anyway, I've been creating custom reports (as needed) in Altiris 6 for years so don't really mind doing the same with ITMS. IT Analytics looks cool and seems similar to creating pivot tables in Excel which, honestly, confuses the heck out of me so perhaps I don't need ITA (hehe).
