Sets the key, sort order, and filter for the data item.
Data items
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.
