Prevent New Categories from Being Added to a Dimension

If you do not want any new categories in your data source added to a particular
dimension, you can prevent this from occurring automatically on category
generation.
For example, suppose you have created a cube group based on one level in a
dimension, and you do not want new categories added to that level; otherwise,
each new category would automatically create a new cube for the cube group. You
prohibit this action.
Procedure
1. Open the property sheet for the applicable dimension.
2. Select Prohibit automatic creation of new categories and click OK.

Verifying Your Model

Cognos Transformer provides a built-in validation tool to help you identify
problems with your model design. Run this tool after each major step in the model
design process, to check for potential problems.
Also, if your model is based on more than one data source, you may find it useful
to generate categories from a specific source, such as the one that supplies your
key structural data or the values for your time dimension, rather than from all the
data sources.
Cognos Transformer automatically checks your model during data import, both
before category generation and before cube creation. Certain warnings, including
some related to auto-partitioning, do not appear with the checks done prior to
cube creation.
Perform the following steps to verify the entire model.
Procedure
1. From the Tools menu, click Check Model.
2. Take note of any error messages. If a Help button is available, click it to locate
