Sets in Tableau

Sets:-

Sets are custom fields you create that are based on existing dimensions, and that filter data using one or more criteria. You can create a set from any existing dimension. When you create a set for continuous dates associated with a relational data source , the set will be based on discrete values rather than a continuous range of values

The three main uses of a set are:

  1)Create a subset of the data: –
        Select one or more dimension members that are of interest to you
  2)Create unique encodings: –
        Combine dimension members to create unique encodings
  3)Save filters for later use: – 
        Once you have created a filter, you can save the filter as a set and use it in all of the worksheets in a workbook. This saves you from having to recreate the filter every time you want to use it.

Tableau displays sets in the Sets area of the Data window and labels them with the 
   icon.
