Define Semiadditive Behavior (Business Intelligence Wizard)
Use the Define Semiadditive Behavior page to enable or disable semi-additive behavior. Semi-additive behavior determines how measures that are contained by a cube are aggregated over a time dimension.
Note
This page does not appear if the Business Intelligence Wizard was started from Dimension Designer or by right-clicking a dimension in Solution Explorer in Business Intelligence Development Studio.
Options
Turn off semiadditive behavior
Disables semi-additive behavior in all measures contained by the cube.The wizard has detected the <dimension name> account dimension, which contains semiadditive members. The server will aggregate members of this dimension according to the semiadditive behavior specified for each account type.
Enables semi-additive behavior for account dimensions that contain semi-additive members. Selecting this option sets the aggregation function of all measures in measure groups that reference the account dimension to ByAccount.For more information about account dimensions, see Account (Analysis Services - Multidimensional Data).
Define semiadditive behavior for individual members
Enables semi-additive behavior and specifies the semi-additive aggregation function for specific measures. The aggregation function applies to all dimensions that are referenced by the measure group that contains the measure.Measures
Displays the name of a measure contained by the cube.Semiadditive Function
Select the aggregation function for the selected measure. The following table lists the aggregation functions that are available.Value
Description
AverageOfChildren
Aggregated by returning the average of the measure's children.
ByAccount
Aggregated by the aggregation function associated with the specified account type of an attribute in an account dimension.
Count
Aggregated using the Count function.
DistinctCount
Aggregated using the DistinctCount function.
FirstChild
Aggregated by returning the measure's first child member.
FirstNonEmpty
Aggregated by returning the measure's first nonempty member.
LastChild
Aggregated by returning the measure's last child member.
LastNonEmpty
Aggregated by returning the measure's last nonempty member.
Max
Aggregated using the Max function.
Min
Aggregated using the Min function.
None
No aggregation performed.
Sum
Aggregated using the Sum function.
Note
Selections made for this option apply only if Define semiadditive behavior for individual members is selected.
