rollup to handle these summarizing operations, such as computing the
mathematical average or taking the last result.
During the modeling process, you should also confirm how duplicate values are
consolidated, and determine if any values need to be allocated to categories, levels,
or dimensions that lack a direct association with these values. For more
information about these important modeling processes, see "Controlling How
Measures Roll Up" on page 100, "Consolidation" on page 107, and "Allocating
Measures" on page 109.
You should also confirm the scale and precision settings ("Scale Input Values" on
page 50) for measures when creating models based on report or package data
sources. Precision settings determine the number of decimal places or significant
digits in your measures. Cognos Transformer brings in scale and precision settings
when they are available. However, when these settings are not available in the
report or package query items, values defined for these settings in the data source
may produce unexpected results. For example, values may produce excessive
rounding or values may not scale correctly when building PowerCubes. In
addition to checking the scale and assigning appropriate precision settings, ensure
you verify that results for query and cube rollup operations in Cognos Transformer
are displayed as you expect.
Note: Cognos Transformer automatically processes queries with measures last.

Add a Regular Measure

Each model contains one or more regular measures; that is, numeric data from a
transactional data source, such as the number of units sold, the cost of goods
purchased, or sales revenue.
The specified query items, including measures, are retrieved from the data sources
specified in your model. After your cubes and data sources are published,
authorized users can access the resulting cubes and OLAP reports for analysis.
For example, the following transactional data source has the regular measures
QUANTITY, REVENUE, and COST. DATE, STORE, and PRODUCT are
non-measure dimensions. Each record represents a sales transaction.
Procedure
To add a regular measure to your model, drag the column from the Data Sources
list to the Measures list.
