You can use parameters: Here's some good info: http://vizwiz.blogspot.com/2012/06/create-global-filter-in-tableau-across.html

and here: http://www.interworks.com/blogs/eshiarla/2011/01/14/filtering-multiple-data-sources-using-parameters-tableau-6

More tricky - I wonder if you would have to resort to custom SQL to join one table with a summary of the second? Maybe there's a way round this with a join instead of a blend and then some magic to fix multiple rows? Difficult to say without an example of your data.

Chris,

Is this your comment at http://vizwiz.blogspot.com/2012/06/create-global-filter-in-tableau-across.html?showComment=1357591191698#c3600400439813736514 ?

Andy alerted it to me, and yes, what you are looking for can be done in a few ways in Tableau.

I normally do it with a data blend, and two worksheets on a dashboard with an action. If you can provide a sample packaged workbook that represents your situation, an example can be created for you.

I just read my comment, and I explained that really poorly. Sorry :(

Hi Chris, have you found a solution yet. I am facing the same issue. I need one single filter in the dashboard that filters data in two sheet.

The selected "correct" approach doesn't work for 8.2

Hi Chelsey

Did you find any solution yet for the above issue ?

I have a similar problem, trying to describe below

-  Sheet-1 uses Data-Source-1

- Sheet-2 uses Data-Source-1

- There are a few common filter values between Sheet-1 and Sheet-2

- Data-Source-1 and Data-Source-2 are at different levels. Based on some common attributes of Data-Source-1 i.e. Sheet-1, i can find some static set up in Data-Source-2

Would be great if i can get some help with this. Let me know if more info is needed as above may not be fully clear

Thanks,

Hi Chris, or Joe,

did you ever find a solution to the issue? I would be very interested to see how you filtered across data sources using normal dimensions (which are shared across data sources) as filters.

Simply blending the data together does not seem to work 100% when I tested it.

Thanks!

Norman
