Semi-Additive Measures (Cost Center Model)

Return to Cost Center Model Overview

The Cost Center cube is set up to handle semi-additive measures. The semi-additive behavior can be declared for elements of the Cost Type dimension and will affect the aggregation along the Month dimension. This can be useful if, in addition to amounts stored in regular accounts, non-additive statistical figures (e.g. FTE or head count) are also added to the Cost Type dimension and thus stored in the Cost Center cube. The semi-additive behavior can be set to Average of children, First child, or Last child (see related article Using Semi-Additive Measures).

For some elements in the Month dimension, exceptions from aggregation behavior have been defined:

Month element	Aggregation inclusion
2015-~, 2016-~, 2017-~, etc.	Data Total: The value will be added to the first, last, or average value of the regular month elements.
2015-00, 2016-00, 2017-00 etc.	Include in First/Last: First child aggregation will be e.g. 2016-00 + 2016-01. First/Last: Last child aggregation will be e.g. 2016-00 + 2016-12.
2015-13, 2015-14, 2015-15, 2015-16, 2016-13, 2015-14, etc.	Remove from First/Last: Last child aggregation will be e.g. 2016-12 but not 2016-13, 2016-14, 2016-15 or 2016-16.
