Tr0904; Tr0906 - IBM Cognos User Manual

You have made changes to the range of dates Cognos Transformer uses to generate
date categories.
Procedure
Ensure that you do not inadvertently change these default values. If the changes
are intentional and you proceed, all the categories in your time dimension will be
deleted.

TR0904

The date level settings could generate in excess of n categories. Do you want to
continue?
Cognos Transformer warns you that it is about to generate an excessively large
number of date categories. This can happen when you have specified a relatively
wide range of dates to include in the generation of date categories and the time
dimension includes low levels, such as Day.
Procedure
In cases where your model requires all these dates, you can ignore this message.
However, if you only need two or three years of data, narrow the range in the
Time tab of the Dimension property sheet before you generate the categories for
your model.

TR0906

The associated column that is specified for dimension dimension_name cannot be
found in the Data Sources list.
Cognos Transformer is unable to find a column to match the one specified as the
column associated with a regular time dimension. This can happen when
v the source file for a data source has changed
v you delete or change the name of a source column
v you change the column name specified on the Time tab of the Time Dimension
Procedure
Ensure that the Column name specified on the Time tab of the Dimension
property sheet matches a column in one or more of your data sources.
TR0907
A dimension was expected but not found. Either you have referred to a dimension
by an object name or object identifier that Cognos Transformer is unable to locate,
or you have not referenced the dimension.
This error occurs when MDL syntax requires an object and is unable to find it. In
this case, the object is a dimension.
The problem may be that the dimension was not referenced, or that it was
referenced with an incorrect object name or object identifier.
