A target drill-through metadata manager has a target drill-through metadata handler and a target specification processor. The target drill-through metadata handler defines and manages target drill-through metadata in a metadata model for model constructs that are selected as drill-through target constructs. The target specification processor processes a target report definition using the target drill-through metadata to locate a data item that refers to a drill-through target construct or part of a drill-through target construct, and automatically adds one or more target filters associated with the drill-through target construct to a target report.

Managing drill-through targets

A mechanism is provided for generating a filter expression using tree parameters receives an expression wherein operators of the expression bind multiple data items to a single parameter to form a received expression, generates a default prompt control using received metadata and the received expression and prompts for an input selection using the default prompt control. Responsive to receiving selected values in response to the default prompt control to form received values the computer-implemented process generates a native database query using the received expression with the single parameter and the received values, wherein the single parameter is a tree parameter.
