Hey Michael -
I just tried the same thing you are having problems with, and everything appears to be working fine - I can use relative date filter against Redshift whether I'm filtering a local, "embedded" data source, or one published out on Tableau Server.
That being said, I AM running a beta of Tableau Desktop and Server version 8.1 - so I may be hitting code that is newer than yours.
I took a quick look through the support team's old cases, and did find one instance of someone having the same issue. They were running 8.04 - you might want to upgrade to 8.05 (or maybe 8.06, which I suspect will be along fairly soon) to see if it makes a difference.
I also see YOU opened up a support case, which was the smart thing to do. The fine folks in support will take good care of you.
Thanks for the fast response, sorry for my slow one. I’ve forwarded all the requested files to your support team. Is there a record of which version that previously reported issue was resolved in? Thanks.
That customer was on 8.04 when the problem occurred. He has gone dark and isn’t responding to our folks asking if things “are good” – which probably means he’s up and running, but doesn’t tell us why ☹
