Hi Robert Bolejszo -- this isn't a noob question at all. It sounds like you're sharing these reports via .twbxs-- is that right? If so, I regret things do not look as rosy as you might want: twbxs utilize Tableau extracts, which are highly structured snapshots of data taken at the time of creation. Unfortunately, the extract remains a snapshot, and because Reader does not have refresh ability, to get the latest & greatest you need to refresh and republish using Desktop or Server.
In order to get the latest up-to-date info, you probably need to be utilizing Tableau Server with either a LIVE connection to the SQL Server (this can cause problems), or one that refreshes upon opening. I don't have much experience with Tableau Server, but I think the refresh-on-open is a feature you can only find there. Server also allows the use of TABCMD, which can allow you to schedule your refreshes.
There are a lot of people smarter than me here-- I recommend searching the forum for similar questions-- I'm sure you'll find this has been asked before!
EDIT: I found this: Re: Can Tableau Reader refresh ODBC data?
Short answer is as I feared: NO, Reader cannot be user to refresh data, only as a one-off for viewing the extracts (snapshots).
