Sets the key, sort order, and filter for the data item.
Use the AssistButton to select the key, sort order, and filter that you want to use.
If you select a key, the report or dataport users cannot select a key, sort order, or filters for the data item.
If you select a sort order, this sort order is suggested as the default when report or dataport users select a sort order.
If you select a filter, this filter is used with user-specified filters in the request form.
Selecting a sort order, a filter, or both, does not prevent users from selecting a key.
