You can select from the following allocation types:
- From Level
With this type, allocation is typically based on values directly derived from a data source.
- Do Not Allocate
This type allocates a single, constant measure value to all descendant categories.
- By Measure
This type allocates values to descendant categories in proportion to a specific measure.
You can allocate measures to dimensions or levels that lack them in the following ways:
- over entire dimensions, when the measure appears in a data source that does not reference the dimension
- over levels in a dimension, when the measure is already specified at a level in that dimension
- over categories in levels, when the measure is specified for the particular level
To allocate measures, you must
- Have a model with two or more data sources.
- Define the measures for that model.
- Create the Dimension Map.
When you have completed the allocation process, you can check the relationships between dimensions and a measure by using the Show Scope command.
You cannot allocate a calculated measure. However, you can allocate a regular measure in proportion to a calculated measure.
To prevent the automatic rollup of constantly allocated measures, you must set a special variable so that the totals in your summary reports are the same as the constants specified for each individual member of a subset.
To do this on Windows, locate the ppds_cfg.xml
file in the installation_location/configuration directory,
open it in any text editor, and add the
with a value of 1 to the
PowerPlay DataServer section
in the following way:
<Section value=PowerPlay DataServer> . . . <DisableConstantAllocationRollup value=1/> </Section>
You can use the ppds_cfg.xml.sample file, also located in installation_location/configuration
directory, as a reference. However, this file does not contain the
