Selection Contexts
In IBM® Cognos® Analysis Studio, this includes the context area. When a package drill-through definition is used, the selection context is used to give values for mapped parameters (parameterized drill-through) or also to map the appropriate data items and values.
Drill-through links can also be defined to open the target object at a bookmark. The content of this bookmark may also specified by the selection context.
Drill-through access is possible between most combinations of the IBM Cognos Business Intelligence studios. Each studio is optimized for the goals and skills of the audience that uses it, and in some cases for the type of data source it is designed for. Therefore, you may need to consider how the various studios manage the selection context when you drill through between objects created in different studios, and how the data sources are conformed. During testing or debugging, you can see how source values are being mapped in different contexts using the drill-through assistant.
