Data Table - Complex Aggregation

We rely heavily on calculated percentages / rates that are embedded within our framework modeler packages, both relational and DMR. Many of these calculations require complex aggregation that entails the percentage / rate (such as return on sales %) to be recalculated at the appropriate level of aggregation to display meaningful results. These calculations function as expected within reporting and dashboarding when inserted directly from the packages. The new Data Tables feature, while very useful, fails to aggregate calculated query items appropriately, instead defaulting to SUM aggregation and incorrectly adds multiple percentages together, returning incorrect values. Data Tables should behave the same as crosstabs and lists, respecting aggregation rules embedded within packages and recalculating percentages / rates at the appropriate aggregation level.
