Customization Models

If you attempt to create an extension and notice that the Create extension option appears dimmed, this is an indication that you need to update your model parameters.
You can update the models that you’re referencing through the Model management option by selecting Update model parameters.

To update model parameters, follow these steps:

  1. In Visual Studio, select the Dynamics 365 menu in the ribbon.
  2. Select the Model Management menu.
  3. Select Update model parameters.
  4. In the Model name field, select your model from the drop-down menu. Select Next.
  5. On the Select referenced packages page, select the box next to the models that you want to reference, meaning the models you want to use to create extensions.
  6. Select Next. You’ll see a summary of the models that you’ve selected.
  7. Select Finish.

Extension models can be created by using the Create model wizard. In the Select package window, select the Create a new package option instead of Select existing package.
