-        - CONTACT_ID, this Field has to contain a CONTACTID. That will be used to find the Connection to your Person or your Organisation.
         - DATE_NEW, this Field has to contain a Date as a Long Value. That will be used as the Date Value you can see in the Timeline View-Template.
         - ACTIVE, in this Field you can specify which Datasets are active or not. You have to declare that in the Value Expression as a Case-When due to the Filter

     - setGroupBy: here you can declare a DB-Column that will be used as the new group by of that context. A good example is Order. We want to group by the Ordertype so we have to declare ORDERTYPE as our groupBy.
