Reverse The Sign Of Measure Values In Financial Models; Cognos Transformer Functions - IBM Cognos User Manual

changed to the current Cognos Transformer default (NA). Upgraded models will
handle missing values in the same way as they did in previous versions of Cognos
Transformer.
To ensure that missing values are shown appropriately, review the missing value
settings for all measures before building new cubes.
Procedure
1. Open the Measure property sheet and click the General tab.
2. In the Missing value box
3. Click OK.

Reverse the Sign of Measure Values in Financial Models

You can reverse the sign of measure values for non-root categories if the sign
would not otherwise make sense to the intended audience.
For example, your accounting system stores revenue and liability balances as
negative values, and expense and asset balances as positive values. You want to
distribute reports based on this data to sales managers, who logically expect
revenue values to be positive. To accommodate the information needs of this
audience, you reverse the sign for revenue values from negative to positive.
Reversing the sign does not affect the value properties, only how they appear in
your OLAP reporting component. However, your report users should be advised
that sign reversal can alter the results of run-time calculations. We recommend that
you state which categories contain reversed signs in the Description box of the
Measure property sheet, thereby ensuring that this important information is shared
with the appropriate users.
To reverse the sign of measure values for specific categories, you must first identify
the measure to be reversed and then select the categories for which the reversal
applies.
Procedure
1. Open the Measure property sheet for the measure whose sign will be reversed
2. Select the Reverse the sign check box and click OK.
3. Open the Categories diagram for the dimension containing the categories you

5. Select the Reverse the sign check box and click OK.
6. Repeat steps 4 and 5 for each category whose sign you want to change.
