NTA prioritizes the processing of filter conditions based on their order of appearance in the Filter
Condition List. In addition, NTA applies filter conditions on a first match first serve basis for all filter
conditions. Filter conditions are matched based on the order of appearance in the filter condition
list and filter conditions are applied from up to down. If a filter condition is matched, the data is
processed according to the matched filter condition without applying the remaining filter
conditions. If no filter condition is matched, the default policy is applied.

• In the Sort field associated with the filter condition you want to move down in the list, click the
icon.
