Allocating Measures - IBM Cognos User Manual

If values for calculated measures are generated before rollup, Cognos Transformer
cannot perform consolidation. However, you can overcome this problem by using
calculated columns. Because such values are always calculated before rollup,
consolidation is again possible.
Procedure
1. Open the Measure property sheet and click the Rollup tab.
2. In the Duplicates rollup box, select a rollup function, and click OK.
3. If you have not yet built your cube, from the Run menu, click Create
4. Open the property sheet for your cube and click the General tab.
5. In the Consolidate box, click Yes (with sort) or Yes (presort).
Example - Consolidating Data Using a Duplicates Rollup of
Average
Although duplicate categories have their measure values summed by default, in
some cases, you may want to specify a different rollup function, such as Average.
For example, suppose the following before-rollup records are duplicates.
The results after Duplicates rollup (Average) are as follows:

Allocating Measures

The Allocation feature distributes data, specified at a summary level of a
dimension, to lower levels. For example, actual sales revenue may be tracked daily,
while sales revenue is forecast quarterly. Allocation is a useful way of distributing
quarterly forecasts to the month and day levels.
You can select from the following allocation types:
v
v
v
If you select Average, you can weight the average by selecting a measure from
the Duplicate weight box.
