An MtmAttributeMap
for an MdmAttribute
whose values are not explicitly stored but are derived from a column or columns in a dimension table. The MdmAttribute
values can be different for each MdmDimension
to which the MdmAttribute
applies.
There are several types of MtmDerivedAttributeMap
objects. You can discover the type of an MtmDerivedAttributeMap
by calling its getDerivedAttributeType
method. Each type maps the tables and expressions for an MdmAttribute
that records different information. The following types are supported:
MdmAttribute
records the ancestor elements for each MdmDimension
element, within each hierarchy.MdmAttribute
records the parent element for each MdmDimension
element, within each hierarchy.MdmAttribute
records the level for each MdmDimension
element, within each hierarchy.MdmAttribute
records, for each MdmDimension
element, integers that indicate the distance from the top of each hierarchy to which the element belongs. The top level is indicated by zero (0), the next level is one (1), and so on.MdmAttribute
records the local value for each MdmDimension
element. The local value is the level value of the dimension. For example, 106
is the local value of an element of the SHIP_TO
level of the SHIPMENTS_ROLLUP
hierarchy of the CUSTOMER
dimension. In the OLAP API, MdmDimension
element values are unique values, which include the name of the hierarchy and the level and the local value, separated by a value separation string, as in SHIPMENTS_ROLLUP::SHIP_TO::106
