inthe link you shared there is a twbx file.https://interworks.com/blog/rcurtis/2017/02/15/tableau-deep-dive-dates-calendar-filters/
you can download the same and change the connection and add your relevant fields instead of redeveloping from scratch.
you can use trick 7 in the link below if you are facing any issues with regards to version of tableau.
hope it helps.
Thanks, I downloaded the file and added one more sheet to check the calendar control, but it is not working.
say for example, in sheet3, I just added Date, OrderDate & sum(quantity) in the row and changed 'All Using this DataSource', but when I select any date from the calendar, it is not reflecting in the report.
I just added the updated *.twb file, but I don't know how to attach in my reply, so I just attached under my original question.
