Setting Data Access Permissions on Dimensions
You can restrict access to data in stories by setting read and write permissions for individual members. You can activate this security feature for any dimension in the model from the dimension Preferences.
You can enable data access restrictions by selecting the Enable Data Access Control check box in the Dimension Preferences dialog. Once this has been activated, two additional columns (Read and Write) are added to the grid of the dimension so that individual settings can be applied to each row. For the Version dimension, a Delete column is added as well as Read and Write columns to control which users can delete each public version.
You can select one or more users (or simply all users) who will have access to the data.
When Data Access Control (DAC) is used with hierarchical data, you may want to use the Hide hierarchy nodes for users without authorization setting.
Using this setting, you can restrict which dimension members can be seen in the Modeler. If this option is enabled, users will see only the members that they have at least Read access to.
|User Role||Expected Behavior|
|SystemOwner||Will be able to see all the members.|
|Admin||Will be able to see all the members.|
|BI Admin||Will be able to see all the members.|
|BI Content Creator||Will be able to see all the members.|
|BI Content Viewer||Will be able to see only the members that they have at least Read access to.|
|Modeler||Will be able to see all the members.|
|Planner Reporter||Will be able to see only the members that they have at least Read access to.|
|Viewer||Will be able to see only the members that they have at least Read access to.|
Consider this example hierarchy:
Canada $110 British Columbia $50 (Read access) Vancouver $40 Kelowna $10 Alberta $60 Calgary $20 (Read access) Edmonton $10 (Read access) Lethbridge $30
DAC is used to restrict access to the members Alberta and Lethbridge.
If you select the Hide hierarchy nodes for users without authorization setting, Alberta and Lethbridge are not shown, and Calgary and Edmonton are moved up to the top hierarchy level:
Canada $50 British Columbia $50 Vancouver $40 Kelowna $10 Calgary $20 Edmonton $10
If you clear the Hide hierarchy nodes for users without authorization setting, Calgary and Edmonton are displayed below their parent member Alberta:
Canada $80 British Columbia $50 Vancouver $40 Kelowna $10 Alberta $30 Calgary $20 Edmonton $10
Depending on which dimension members users are authorized to see, the aggregated value for Alberta can be different for different users, which could be misleading. For example, if User A has read access to Lethbridge, but User B does not, then User A would see an aggregated value of $60 for Alberta, while User B would see $30.
- Select the dimension that you want to modify and choose on the toolbar.
- Select the Enable Data Access Control check box.
- Select the Hide hierarchy nodes for users without authorization check box if desired (see above note).
The Read and Write columns are added to the dimension grid.
You can now use the two new columns Read and
Write to control access to all rows of the grid by
selecting one or more users in either or both of the columns.
Each user who is granted Write access for a member automatically receives permission to read the data as well. Likewise, a user who receives the Delete permission for a member of the Version dimension also receives Read and Write permissions for it.
