In this step of the View creation wizard, the columns are automatically pre-classified as Case or Event columns. Change the classification of columns, if needed.

Event columns are attributes that are specific to a single event, for example, the cost of an event or a rejection reason for a rejection event. Case columns are attributes that are common to every event within a Case, such as the City, State, Case Type, Client Type, and more. Labeling these columns correctly impacts the results of the analysis and metrics.

You can change the classification of one column by clicking its name or change all columns from one classification to another by clicking the double arrow button.

You can also filter the columns displayed on each section by entering the search text in the search field. At the bottom of the tab, a preview table shows all of the columns, as shown in the following figure:
In the View creation wizard, the Group tab shows the columns organized by Event type or Case type and provides options to change the type of any column.
