IBM Cognos Transformer Version 10.1.1: User Guide
<Preference Name="IncUpdateWarnings" Value="TRUE"/>
This setting issues warnings when an event is going to take place that will make
an incrementally updated cube invalid; for example, deleting a category. The
default value of TRUE means that warnings are issued; FALSE disables
warnings.
<Preference Name="ChildRatioThreshold" Value="35"/>
This setting issues a warning if the number of child categories for any parent
category exceeds the specified value. Valid values are 1 through 16384. The
default is 35.
<Preference Name="MaxTransactionNum" Value="50000"/>
This setting specifies how often Cognos Transformer creates checkpoints for
recovery from severe errors during cube creation. This is defined as the number
of records written to a cube before a new checkpoint is created. If your data
sources are constructed from a database, this value shouldn't exceed the size of
your database rollback journal. The default is 500000.
<Preference Name="DecimalPoint" Value="."/>
This setting specifies the character used as a decimal point in a data source. The
default is a period (.).
<Preference Name="DefaultSeparator" Value=","/>
This setting specifies the field delimiter in a delimited-text data file. The default
is a comma (,).
<Preference Name="ThousandSeparator" Value=","/>
This setting specifies the character used as a thousands separator in a data
source. The default is a comma (,).
<Preference Name="CenturyBreak" Value="20"/>
This setting specifies the cut-off date that determines whether the two-digit year
(YY) in a six-digit date is a 20th or 21st century date. Cognos Transformer
interprets values below the cut-off as 21st century dates and values at or above
the cut-off as 20th century dates. The default is 20.
Because 00 to 19 are automatically treated as 21st century dates and 20 to 99 as
20th century dates, you only need to change the default if your data source
includes dates from 1900 to 1919. For example, the setting CenturyBreak=18
means that the values 00 to 17 are interpreted as 2000 to 2017 and the values 18
to 99 are interpreted as 1918 to 1999.
This setting controls the format in which the date is displayed. It determines
whether users can view dates in a cube in lunar year format. The value TRUE
indicates that the dates will be displayed in this format. A value of FALSE
indicates that dates will be displayed in calendar year format.
