MJ: Your pretty much informing me to setup a schedule for processing in order to keep the info I want to report against up to date?
IP: Since ITA reports don't get latest data from managed resources via NSE files that arrived to NS, ITA has processing task per checked 'Cube' to get latest data from Symantec database into ITA report database. So you will need to set correct schedule to make sure that your 'gather inventory', etc tasks are done and Symantec database has latest information, after that will be good to execute ITA reports processing to populate there latest data as well.
MJ: When I right-click on the fnITA what am I choosing? Script Function As, New Inline Table Valued Function, etc? Forgive me, sql and sql studio have not been my area of expertise.
IP: Right click on each ITA function -> Modify -> you'll see content (If you will save each function content with it's name as .txt, then send me them all via private message, I'll compare them with my as soon as possible)
