Two Model Driven Apps Vs Security Permissions

Posted on by JF000001

I have two groups of users who will be using a Dynamics 365 customized App, each of which should have access to all tables, but using a different navigation scheme. It appears that there are two schools of thought on how to implement such a scenario.

i) Create two model driven apps based on the same App (same Database), but configure each App with a different Sitemap;

ii) Configure permissions so that Group1 has access to some menu items, while Group2 has access to different menu items (but without affecting table access).

What is Microsoft's recommended approach in such a scenario?

Thank you. JF

I would not recommend your second option, and I'm honestly not entirely sure how it would even work. When an item is added to a Model Driven App navigation, the only way to determine whether it appears for a user or not (without some crazy overlay on the whole app) is by setting Read permissions for the table in the security role. This means if both groups of users need to be able to read and access the table, this approach would be a non-starter from my perspective.

Creating two model driven apps, one for each group, is an easy approach and I would strongly recommend going that way. You can control access to Model Driven apps based on security role, so each group only sees the app they are supposed to see. If security roles aren't already split for each group (meaning they share roles), then you can create custom roles just for each app access and assign it that way as needed.
