Specifying the default position of aggregate values
The default location of aggregate values is in a group’s header. To place aggregate values in a group’s footer, set EnableNewAggregationStyle to false in erni_config.xml:
<featureConfigs>
  <featureConfig>
    <name>EnableNewAggregationStyle</name>
    <value>false</value>
  </featureConfig>
...
</featureConfigs>
