Part Number A95295-02
A level is an OLAP metadata entity. This means that it is a logical object, identified by name and owner, within the OLAP Catalog.
Dimension members are organized in levels that map to columns in dimension tables or views. Levels are typically organized in hierarchies. Every dimension must have at least one level. Levels are fully described in "OLAP Metadata Model"
Use the procedures in the
CWM2_OLAP_LEVEL package to create, drop, and lock levels, to assign levels to hierarchies, and to specify descriptive information for display purposes.
The parent dimension and the parent hierarchy must already exist in the OLAP Catalog before you can create a level.
