Tip: Because the consolidation process runs against every source file in your
model, ensure that your temporary file space is at least as large as the sum of all
your source files.
Procedure
1. Open the PowerCube property sheet for the cube that you want to consolidate
2. In the Consolidate box, click the appropriate entry in the drop-down list:
3. Click OK.
Disable the Category Refresh Option
For large complex models, you may improve processing by disabling the options
that refresh the category information.
If this information subsequently changes in your source data, remember to enable
the refresh options again before regenerating your categories.
Procedure
1. Open the appropriate Level property sheet so that you can disable its refresh
2. Clear the Refresh check boxes for Label, Description, and Short Name.
3. Click OK.
Delete Inactive Categories
If your organization changes, you can delete inactive categories that are no longer
needed in your model.
A category is only considered active if it has been created, updated, moved, or had
its properties changed after the date you specify.
For example, suppose that last year your department was responsible for
inspecting 40 homes for the elderly. After a consolidation of facilities, you now
inspect and report on the operations of only 30 homes. You delete the categories
for the 10 homes that have been closed since the start of your fiscal year.
The Clean House feature should be used with caution, as it may cause problems
with consumers' reports in IBM Cognos. If you intend to delete inactive categories,
we recommend that you advise your consumers so that they can remove those
categories, or members, from their reports when they are directly referenced.
Otherwise, they may receive an error the next time they run their reports.
You cannot delete inactive categories if incremental updates are defined for the
cubes in your model. If you do, an error message will appear when you try to
create the cube.
Procedure
1. From the Tools menu, click Clean House.
2. In the Date box, type a date using the format configured for your system or
