What is the first step required to create a simple user interface for a custom data model in MDG?

Creating a user interface for a custom data model in SAP Master Data Governance (MDG) typically begins with establishing the necessary connectivity and communication settings, which is what the MDG communicator settings entail. These settings are crucial because they allow the MDG system to interact effectively with the user interface components and ensure seamless data flows between different parts of the application.

Establishing MDG communicator settings sets the foundation for further steps, such as assigning application configurations and creating user interface elements that will respond to user inputs effectively. Having these settings in place ensures that subsequent configurations and customizations can access the appropriate data and services required for a functional user interface.

Options involving assignment of application configurations or creating deep copies of templates come afterwards as they typically depend on the foundational communication infrastructure to operate properly. User authorization settings, while important for security and access control, also come into play later in the process after the UI framework has been established.
