Selecting initial summarization levels
Assigning a particular summarization level in the sort criteria as the initial summarization level, signifies that this is the level for which summary information is to be shown when the results form is first displayed. Other summary detail may then be displayed within the form using the implode and explode functionality.
When summarization levels are selected, the default initial summarization level is the first sort criteria displayed in the list in the filter edit area. This can be amended to any of the summarization levels, or can be deselected altogether.
