  The SAP error message MDG_DT_DATA_MODEL047 indicates that you are trying to create or modify a data model in the SAP namespace, which is not allowed. In SAP, the standard namespaces are reserved for SAP's own development, and custom developments should be done in customer namespaces, which typically start with Z, Y, or X*.
  Cause:
  The error occurs when:
  
  You attempt to create or modify a data model in the SAP namespace (e.g., starting with "SAP").
  The system restricts changes to standard objects to prevent conflicts and maintain system integrity.
  
  Solution:
  To resolve this error, you should:
  
  Use a Custom Namespace: Ensure that you are using a custom namespace for your data model. This means you should start your data model name with Z, Y, or X*.
  Create a New Data Model: If you have already created a data model in the SAP namespace, you will need to create a new one in your custom namespace.
  Check Naming Conventions: Make sure that the naming conventions you are using comply with SAP's guidelines for custom developments.
  
  Related Information:
  
  Namespaces: In SAP, namespaces are used to differentiate between standard SAP objects and custom objects. The standard namespace is reserved for SAP, while customer namespaces (Z, Y, X*) are for custom developments.

  SAP Notes and Documentation: You can refer to SAP Notes or the official SAP documentation for more detailed information on data modeling and namespace usage.
  
  Steps to Create a Custom Data Model:
