The collection of Annotations on the current Data Coverage Definition.
[Browsable(true)]
public AnnotationCollection Annotations { get; }
Property Value
DefaultExpressionProperty
Gets the default expression property on the current object.
[Browsable(false)]
public ExpressionProperty? DefaultExpressionProperty { get; }
Property Value
Description
The description of the DataCoverageDefinition, visible to developers at design time and to administrators in management tools, such as SQL Server Management Studio.
public string Description { get; set; }
Property Value
ErrorMessage
The string that explains the error state associated with the DataCoverageDefinition. It is set by the engine only when the state of the Expression is one of these four values: EvaluationError, SemanticError, DependencyError or SyntaxError.
public string ErrorMessage { get; }
Property Value
Expression
The DAX expression that is evaluated for the DataCoverageDefinition.
public string Expression { get; set; }
Property Value
[Browsable(false)]
public int MetadataIndex { get; }
Property Value
Name
[Browsable(false)]
public string Name { get; set; }
Property Value
Partition
A reference to the Partition object that owns the DataCoverageDefinition.
public Partition Partition { get; }
Property Value
State
Provides information on the state of the Expression. Possible values and their interpretation are as follows. Ready (1) The Expression is queryable and has up-to-date data. CalculationNeeded (4): The Expression is not queryable and needs to be refreshed to become functional. SemanticError (5) The Expression has a semantic error. DependencyError (7) A dependency associated with the Expression is in an error state (SemanticError, EvaluationError, or DependencyError). SyntaxError (9) The Expression has a syntax error.
