This sounds odd. What version of Tableau Desktop and Server are you using? Are you able to post the packaged workbook where you are seeing the issue?
Thanks for your reply. I am using Tableau 8.
You mean post it to server? Yes I am able to post it / publish it to server. The workbook gets published fine, but the table / view that is updated on database is not updated (only) in the published workbook on server, even though it looks fine on tableau desktop. It is missing one of the fields in one of the tables that got updated recently. Basically, it wouldn't refresh and pick up the new field from the table.
