Data type attributes (PEL)
A PerformancePoint Expression Language (PEL) data type consists of a basic type, and a set of data type attributes. An attribute represents a constraint on a data type. Each basic type has three attributes: Dimension, Hierarchy, and Level. Level is the most constraining, next is Hierarchy, and last is Dimension. For example, if a basic type is constrained to a particular Level, it is also constrained to a particular Hierarchy and Dimension. Similarly, if a basic type is constrained to a particular Hierarchy, it will also be constrained to a particular Dimension.
Except as noted, all attributes are INDETERMINATE. The following list shows the three ways attributes can be literal.
A Hierarchy can be constrained to a literal Dimension.
A Level can be constrained a literal Hierarchy.
A MemberSet can be constrained a literal Level.
For example, the [Time].[Calendar].[Months].[January 2006] member has the following attributes:
DIMENSION is [Time]
HIERARCHY is [Time].[Calendar]
LEVEL is [Time].[Calendar].[Months]
