Without a sample workbook, it is hard to be sure if this will work but I suggest reading this - Filtering the View Without Filtering Underlying Data | Tableau Software and trying the lookup() method described. A table calculation can be used to filter the view on screen without filtering the underlying data from the view.
Give it at try and if it doesn't work, I suggest just taking a small amount of data and creating a sample viz from the existing one. You could also try the method described here: Anonymize your Tableau Package Data for Sharing.
I hope this helps.
