Model-driven app frequently asked questions
These frequently asked questions (FAQ) can help you resolve issues that might occur when you work with model-driven apps.
How do I run a model-driven app?
In order to play an app you need to have a security role assigned to you and the URL to the app.
To share the app, select the app, and then on the command bar select ... > Share. The app sharing page as shown below appears for you to assign a security role.
You can find the app URL using the process below.
To play the app, open the URL in your browser.

Why can't I create a model-driven app?
The most common reasons you can't create model-driven apps are:
- Environment configuration
A Power Apps or Dynamics 365 license is required to create a model-driven app. More information: Licensing requirements for tables in the Power Apps Licensing Guide and Understanding Power Platform Licensing
Make sure you have sufficient privilege to create model-driven apps in your environment. More information:
Additionally, you might be working with a restricted table. The following Dynamics 365 customer engagement applications include restricted tables:
- Dynamics 365 Sales
- Dynamics 365 Customer Service
- Dynamics 365 Field Service
- Dynamics 365 Marketing
- Dynamics 365 Project Service Automation
Make sure you have the appropriate Dynamics 365 application license when working with these tables. More information: Restricted tables
Why can't you see my model-driven app?
Make sure you have the appropriate privileges on the app. Work with your app maker or admin to ensure you have the proper security roles for the app. More information:
Why don't I see my model-driven app changes?
Make sure you publish your app customizations. More information:
Also, verify your component changes in the active layer. You can use the solution layer feature in Power Apps to review solution layering for a component. More information: View the solution layers for a component
How do I add more tables to my app?
The site map defines the navigation for your model-driven app. You add tables to a model-driven app's site map by using the site map designer. Tables that aren't included in the site map won't be available in your app. More information: Create a model-driven app site map using the site map designer
How do I share my app?
You use security roles that contain the appropriate privileges and assign them to the users, teams, and apps you want. More information: Share a model-driven app using Power Apps
Why don't I see all the views after importing a solution?
A model-driven app change that was made by selecting All when selecting a component, such as a view, isn't reflected after importing an update to the app in the target environment. More information: Newly added components don't appear in the app after importing an update to the app
What's the best way to define and manage my model-driven app?
We recommend that you create your app in a dedicated solution. By creating a solution for your app, you can maintain your other solutions without creating any dependencies with your app. Only make changes to that solution when you want to update your app—for example, when you add, change, or remove components from the app. More information: Create a solution
More advanced users can review the solution's customization.xml file. When you import a managed solution, customizations.xml might include the
solutionaction property when you add and remove components. The possible values for
This value specifies the changes in the current layer with respect to the previous managed layer. For example, on solution import,
solutionAction="Removed" will remove the component from the app. More information: Microsoft.Crm.CrmInvalidOperationException: full formXml is expected to create a form <formid> message during solution import
What is an app module?
The term app module has been used to describe model-driven apps, and
appmodule is the name referenced in the Microsoft Dataverse and customer engagement apps schema. Model-Driven App is included in the display names for some of the tables referenced in Power Apps. For information about the
appmodule table, go to AppModule entity reference. For information about using the
appmodule table API, go to Create, manage, and publish model-driven apps using code.
App modules, which are referred to as model-driven apps in Power Apps, are created and customized within a solution. Solutions are used for application lifecycle management, and you can use them to migrate customizations from one environment to another. It's beneficial to be familiar with the solution layering concepts.
