Resolved: What Usage is for Bookmark?
This lesson is a bit confusing. I don't know what bookmarks are used for in the report. Thanks!
they are used to capture a state of the report, imagine you have plenty of filters applied and you want to be able to quickly clear all the filters and return to the default state of the report. This can be achieved by using Bookmarks, so you create a bookmark of the report without any filters, then you create a button and add an action to the button to clear all filters.
