Subsets
A subset takes the button and all its underlying content and filters out data that is irrelevant to a single value. Subsets save a single dimension value taken from a child free-form data page, and later applies it to the page and all linked or associated pages.
A subset is also only available to the user who created it.
Bookmarks can save multiple filters for a specific data page of any type, and return to that specific data page with the filters applied. A subset filters with a single dimension value and applies that filter to all button content.
NOTE: Whether a linked free-form data page can create a subset is determined by the developer.
Here is the example Overview free-form data page.
Here is the same page with the subset, Supplier: CONSTELLATION, applied.
Notice the difference in numbers.
NOTE: The subset has the full functionality of the button content, but focuses on specific data.
