CompositionRelevanceExpression: IExpression;
CompositionRelevanceExpression: Prognoz.Platform.Interop.ForeSystem.IExpression;
The CompositionRelevanceExpression property determines an expression for calculating aggregation relevance.
When this expression is set, the IMsCrossDimensionAggregationOptions.Threshold property value must be determined. If the sum of the CompositionRelevanceExpression values, divided by the sum of all values is less then the IMsCrossDimensionAggregationOptions.Threshold value, the aggregation is not calculated.
The collection of the elements, which can be used in the expression, is returned by the IMsCrossDimensionAggregationTransform.CompositionRelevanceOperands property.
The property use is given in the example for IMsCrossDimensionAggregationTransform.AppliesToExpression.
