Set A Duplicates Rollup Function For Measures - IBM Cognos User Manual

Suppose your source data contains daily transaction records such as the following,
which are used to create the Date and Region dimensions.
Because the Degree of detail is set to Month, day values are ignored. Records for
the same month and store are consolidated (summed).
The results after Duplicates rollup (Sum) are as follows.
After Regular rollup (Average), the monthly records for each Store in the East
region are consolidated again.
Your cube has a dimension view where store values are aggregated to the East
level.

Set a Duplicates Rollup Function for Measures

The Duplicates rollup function specifies how records containing identical
non-measure values (category names) are aggregated. The records may or may not
have different measure values.
The default Duplicates rollup for each measure is None (Regular rollup).
However, you can change the setting to Sum, Minimum, Maximum, Average,
First, or Last.
You can explicitly request consolidation by changing the Consolidate setting on
the General tab of the PowerCube property sheet.
