Creating dependent relational selections with a hyperblock
You can control the data of a relational selection in a hyperblock through other objects (for example, an additional hyperblock). The other display object may be based on a multidimensional or a relational list.
Both databases must have corresponding values or data fields. For example, the multidimensional data source has a Region dimension, and the relational datasource a Country column, and one or more regions have the same name as countries in the relational datasource.
