In the Model Manager, there is not the option to select a Mandatory Enforced property. In order to implement a mandatory enforced property, one must deploy the model through BootStrap or Dynamic deployment.
Customer is requesting the ability to select if a Mandatory property should be enforced through the Model Manager.
The users who have access to Model Manager and create content models, may not have access to the file system level to be able to Bootstrap deploy a content model. Being a production environment, using the Dynamic deployment method is also not an ideal situation.
This is the reason for having the ability to select if a Mandatory property is to be enforced directly from Model Manager.
