Add
• Deletes all existing user views
• Reads database
• Creates new views
• Build cubes from batch file
Build • Copy and deploy cubes
VB.NET code – what does
it do?
For intX = 1 To dimension.DrillDowns.Item(1).
Categories.Count
Dim category As Category =
dimension.DrillDowns.Item(1).Categories(intX)
If category.Name = deptName Then
view.SetViewStatus(category,xtrViewStatus.t
rViewStatusApexAncestor)
End If
Next intX
The end result
 No
manual maintenance of Transformer
security
 Security preserved in all Cognos tools –
relational, dimensionally modeled
relational (DRM), and cubes
 No more headaches for BI team!
