Base element for hierarchy elements within a dimension.
The hierarchy is an abstract element that defines the basic properties of a OLAP hierarchy element. The derived elements, tabular and ODA hierarchy elements, provide level contents that are defined in this hierarchy itself.
Filter criteria to apply to query result in the hierarchy element.
The filter property specifies filter criteria to apply to each row in the data set. The filter can contain BIRT expressions (in JavaScript.) If you want the database to do the filtering, put the filter criteria in the WHERE clause of your query.
