Resolving Model-Driven App Access Issues via Security Roles
Short answer
C Assign users the appropriate security roles to grant the necessary Dataverse privileges for accessing and recording financial data in the model-driven app.
Question
The app is currently visible in the app launcher but inaccessible to the accounting team.
Users must be able to:
Open the app.
Access and record financial data.
You need to resolve the access issues.
What should you do?
Key Takeaways
App visibility in the launcher does not equate to data access; security roles must be assigned to grant the specific table privileges needed for interaction.
Learn how to resolve inaccessible model-driven apps by assigning proper Dataverse security roles to users, ensuring they have the required privileges to view and edit data.
Common mistake: Selecting 'Configure app visibility privileges' (A) is incorrect because the app is already visible in the launcher. Users need data access, not just visibility.
Expert Analysis
The core issue in this scenario is a permissions boundary within Microsoft Dataverse, which underpins model-driven apps. While app visibility controls whether an application appears in the App Launcher, it does not grant access to the underlying data or business logic. The accounting team can see the app but cannot interact with it because they lack the necessary privileges to read, write, or record financial data.
Security roles are the primary mechanism for defining these privileges in Dataverse. A security role aggregates specific privileges (such as Read, Write, Append, or Create) for individual tables and columns. By assigning the appropriate security role to the users, you explicitly grant them the rights to perform actions on the required entities. Without this assignment, even if the app is visible, the system will deny access to the data records.
It is crucial to distinguish between option C and option D. Table-level permissions are configured within a security role. You do not assign table permissions directly to users; instead, you assign the security role that contains those permissions. Therefore, configuring table-level permissions (Option D) is a step taken while designing the role, not the final action to resolve user access. Option A addresses visibility, which is already satisfied since the app is in the launcher. Option B sets the default view but does not address the fundamental access denial. Thus, assigning the correct security role is the decisive action.

Exam Strategy
When troubleshooting access issues in Power Platform, always separate 'visibility' from 'permissions'. If an app is visible but users cannot act, check their security roles first. Remember that security roles are the container for all table and column privileges; you assign roles to users, not individual permissions directly. This distinction is critical for questions involving Dataverse security models.
