Chapter 7. Dimensional security 175
7.8.6 Example 5
This example shows how merging two views can require secured padding members.
Security view 1
Figure 7-48 shows granting Americas, and granting United States and descendants.
Figure 7-48 Security view 1: Grant America, grant United States and descendants
176 IBM Cognos Dynamic Cubes
Security view 2
Figure 7-49 shows denying United States and descendants.
Figure 7-49 Security view 2: Deny United States and descendants
Figure 7-50 shows the consolidated view for a user assigned to both the views.
Figure 7-50 Consolidated view for a user assigned to both the views
The default member is Americas, and All member is a visible ancestor. While neither security
view 1 or security view 2 had padding members, their consolidated view requires padding
members to stay balanced.
