问题
I am creating a report in Tableau and wanted to show the latest date in dashboard whenever I refresh the data. My data also contains last one month's data points. And on daily basis, we are refreshing the data.

If you just want to show the latest date in your dashboard you can just have a sheet with max(date_field) and drag that sheet onto your dashboard. If you want that date to change dynamically with the users choice of periods that you just need to look at "Apply to worksheets" on your dashboard filter.
