Essbase users can define rules that select dimension member subsets by rules composed of data source constructs:
Generation—Members belonging to a specified generation of the dimension hierarchy
Level—Members belonging to a specified level of the dimensional hierarchy
Expression—Members matching a pattern of wildcard characters
Attribute dimensions—Members with a specified database-defined attribute
Conditional logic—Members satisfying advanced subset member selection criteria
You can search all selected member descendants using a maximum of 50 subset conditions. Subset criteria are saved by individual document. Because the filter panel cannot accommodate lengthy selection lists, subset member selections made in Filters are summarized with a description.
