Master-detail optimization in reports based on data modules

Currently, Master-detail optimization is the feature that has to be explicitly enabled by turning on a specific FM DQM governor and publishing the FM package.

Without that feature turned on, most reports and burst reports containing master-detail relationships would run inefficiently by re-issuing the detail query for each and every record in the master dataset.


Since there is currently no way to turn on this feature with data server data modules. Such master-detail reports based on data modules might be inferior in terms of performance, and possibly would have to be rebuilt out of a venerable FM package.
