Omit Dimensions From A Cube; Customizing Cube Content With Views - IBM Cognos User Manual

Tip: Be careful not to exclude measures that are used in the calculation of other
measures used in the model. Otherwise, errors may occur when your cube is
created or updated.
Procedure
1. On the PowerCube property sheet, click the Measures tab.
2. Right-click a measure and click Exclude.
3. Click OK.

Omit Dimensions from a Cube

You can omit specific dimensions from a cube to customize it for particular users.
You can omit a dimension from the cube entirely, or you can include it but hide it
from specific users.
For example, suppose your model uses several data sources to provide information
about every facet of your sporting goods business. The source columns are
Product, Customer, Branch, and Order, with each having a corresponding
dimension. You want one of your cubes to focus on product sales performance.
Because you do not need customer data, you omit that dimension from the cube.
For models with authentication enabled, you must use the Categories diagram to
hide a dimension from a user group, rather than omit it from the cube. In such
cases, the dimension is retained in the cube but restricted users cannot access it.
Procedure
1. On the PowerCube property sheet, click the Dimensions tab.
2. Right-click a dimension to omit or hide and click Omit Dimension.
3. Click OK.
