What measure you used in desktop and server.
i think you have used non aggregated data like ID as measure here.
We could better advise if you share details like : What is the data source? What is the nature of the Measure in question (e.g. is it a Calculated Field? Is it an integer or a float ?) What versions of Tableau Desktop and Tableau Server were used?
Even better, Ken, Jaseema should post a sample workbook.
Jaseema -- pare down your workbook to the minimum that will demonstrate the problem. (Probably just one sheet on one dashboard) and anonymize your data as shows in this video:
You'll probably need only a handful of records.
Actually, it often happens that in going through this exercise you find the problem once it's all simplified. But if not, then you can post it here and people can look at it hands-on and help you find the issue.
