Level Expressions (MDX)
In InterSystems MDX, a level expression has one of the following forms:
A level literal, which is a direct reference to the level as follows:
[dimension_name] is an MDX identifier that names a dimension.
[hierarchy_name] is an MDX identifier that names a hierarchy within that dimension. You can omit the hierarchy name. If you do, the query uses the first level with the given name, as defined in this dimension.
[level_name] is an MDX identifier that names a level within that hierarchy.
