CUBE_NAME	DBTYPE_WSTR		The name of the cube to which this measure belongs.
MEASURE_NAME	DBTYPE_WSTR		The name of the measure.
MEASURE_UNIQUE_NAME	DBTYPE_WSTR		The Unique name of the measure. For providers that generate unique names by qualification, each component of this name is delimited.

MEASURE_GUID	DBTYPE_GUID		Not supported.
MEASURE_AGGREGATOR	DBTYPE_I4		An enumeration that identifies how a measure was derived. Can be one of the following values: MDMEASURE_AGGR_SUM (1) MDMEASURE_AGGR_COUNT (2) MDMEASURE_AGGR_MIN (3) MDMEASURE_AGGR_MAX (4) MDMEASURE_AGGR_AVG (5) MDMEASURE_AGGR_VAR (6) MDMEASURE_AGGR_STD (7) identifies that the measure was derived from an aggregation function that was SUM, COUNT, MIN, MAX, AVG, VAR, or STDEV, respectively. MDMEASURE_AGGR_CALCULATED (127) identifies that the measure was derived from a formula that was not any single function above. MDMEASURE_AGGR_UNKNOWN (0) identifies that the measure was derived from an unknown aggregation function or formula.
DATA_TYPE	DBTYPE_UI2		The data type of the measure.
NUMERIC_PRECISION	DBTYPE_UI2		The maximum precision of the property if the measure object's data type is exact numeric. NULL for all other property types.
NUMERIC_SCALE	DBTYPE_I2		The number of digits to the right of the decimal point if the measure object's type indicator is DBTYPE_NUMERIC or DBTYPE_DECIMAL. Otherwise, this value is NULL.
MEASURE_UNITS	DBTYPE_WSTR		Not supported
DESCRIPTION	DBTYPE_WSTR		A human-readable description of the measure. NULL if no description exists.
EXPRESSION	DBTYPE_WSTR		An expression for the member.
