Drill-through enhancements
The dashboard drill-through definition dialog box was enhanced to improve the user experience with parameters. The list of parameters in the drill-through definition is now sorted, with the broken parameters shown at the beginning. A filter is also added that allows to display the parameters based on their mapping state.
Parameters with broken mappings are shown first, followed by unmapped parameters, and then by mapped parameters. The Filter by mapping state drop-down menu allows users to view only broken, unmapped, or mapped parameters. By default, all parameters are shown.

Mapping errors in the dashboard drill-through definition occur when the report author changes the name of a parameter, or changes the data item that the parameter refers to. In previous versions of the product, trying to find the mappings with errors in a long list of mappings was tedious. With the current user interface enhancements this task is much easier.
