Example of data aggregation from daily to weekly frequencyAssembly: Ms;
The IMsCollapseTransform interface contains properties and methods that determine parameters of the Collapse model.
IMsCollapseTransform
This model aggregates lower level data to upper level; it is used to calculate problems that require data aggregation. For example, data calculated by months must be summed for quarterly frequency.
On data aggregation the following calendar frequency settings are taken into account by the model: shifting start period relative to its start/end.
