Remarks

The flag name may contain spaces. The natively-supported values are listed in the following table.

Value Description
MODEL_EXISTENCE_ONLY The column should be modeled as having two states, missing and nonmissing, regardless of the values in the column. This is particularly useful for columns in a nested table, where values are sparse across cases.
NOT NULL The column cannot accept NULL values.
REGRESSOR The column supplies regressor values for test cases.

Additional provider-specific flags may be used if third-party OLE DB or data mining providers have been aggregated on the instance of Analysis Services.

A closely related element in the Analysis Management Objects (AMO) object model is MiningModelingFlags.
