For every planning model, security set up is a must. Many models have shared public dimensions on which the security set up needs to be done. Security set up can be done via various options but the most popular one is via Data Access Control (DAC). In cases where a user needs to access multiple models which share a public dimension on which security needs to be defined, this could be a problematic situation because the user might get access to cost centers for a particular model in which the access should not be granted. The below scenario illustrates such an example and how model data security can solve this situation.
Expense model and HR model share a public dimension called cost_center on which the data security needs to be defined for both the models. A user should have write access to only CC_1 in Expense model and should have write access to only CC_2 in HR model.
If Data Access Control of cost center dimension is utilized to control the security for both the models, then the user will have access to CC_2 in Expense model while CC_1 in HR model which is not desirable.
The user is able to edit both the cost centers i.e., CC_1, CC_2 in both the models whereas only CC_1 should be editable for Expense model and CC_2 for HR model. Below is an example of how the expense template would look like with such a security set up.
How to solve such a problem? The solution lies with the Model Data Privacy setting in the model.
Note: For all practical purposes, CC_1 cost center would not have any data for HR model because CC_1 would not be a HR related cost center and visa versa. Nevertheless, the user can accidently, input data for CC_1 cost center in HR model so, it is best to not to show up this cost center in the HR model to avoid any erroneous entries.
Step 1: Turn on the model data privacy for both the models.
Step 2: Create two separate custom properties for security definition for the 2 models in the public dimension i.e. cost center. In this example “Security for HR” property is for maintaining security for HR model while “Security for Expense” is for Expense model. Any property can be utilized including standard property. Maintain the users as per data access.
Note: Multiple users and/or team can also be added as shown below:
Step 3: In the role assigned to the users, click on “Select Model”.
Maintain the security as defined below for write access.
The above screenshot is for HR model. The same needs to be done for Expense model.
TIP: Copy the standard role to customize as per the requirement.
Note: For team, follow the below steps
Now, our setting for security is complete, let us see the output in the input templates.
Let us see how the data is stored in HR model and how is it visible to the HR user who has access to CC_2 cost center only.

Similarly, for expense model, only CC_1 would be visible.
Note: In case the unbooked data for cost center dimension is turned on for the input template, the unbooked cost centers for which the access is not provided will also show up but when an entry is tried to be made on those cost centers the data would not be published and following message will show up.
Note: If data access control is also enabled along with model data privacy then both will be effective simultaneously.
In this blog, you have learnt to set up access to data regions for models which have security based on public dimensions via model data privacy settings. Hope this blog will help you to find an alternative and effective way to resolve data access issues when security of multiple models is based on common public dimension.
