Groups and Filters are both tools for isolating and extracting interesting data and reusing it in dashboards and analytics.

Groups

Groups are a list of explicitly selected Members from a single Dimension.  For example, the months January, February and March can be collected into a Group called ‘First Quarter’.  The products Cheese, Milk, and Ice Cream can be collected into a Group called ‘Dairy Products’, and so on.

Filters

Filters are a dynamic list of Members that meet specified criteria.  Unlike Groups that always hold the same explicit Members, Filters determine the list of Members that meet their specified criteria at the moment the request was made.  Examples of Filters are ‘Products bought by more than 3 customers’ and ‘Customers who visited Store A but not Store B’.

 

Both Groups and Filters let you easily access Members in a Dimension that have something in common and use them in a dashboards or analytics.  Once you define the Members you want to collect, you can give the collection a descriptive name and reuse it in future documents.
Moreover, Filters are a powerful tool in their own right because they provide a straightforward yet powerful way of extracting information that would otherwise be very difficult to access.
