Smart SAP Assistant

• What is the cause and solution for SAP error message MDG_DT_DATA_MODEL134 - Models with X*/Y*/Z* names cannot be edited in delivery landscape ?

  The SAP error message MDG_DT_DATA_MODEL134 indicates that you are trying to edit data models with names starting with X, Y, or Z* in the delivery landscape of SAP Master Data Governance (MDG). In SAP, certain naming conventions are reserved for customer-specific developments, and models with these prefixes are typically not editable in the standard delivery landscape.
  Cause:
  
  Naming Convention: The error arises because SAP restricts editing of data models that begin with X, Y, or Z in the standard delivery landscape. These prefixes are generally used for customer-specific developments and modifications.
  Delivery Landscape: The delivery landscape refers to the standard SAP system environment that is delivered to customers. Editing certain models in this environment is restricted to maintain system integrity and avoid conflicts with standard SAP functionality.
  
  Solution:
  
  Use a Custom Namespace: If you need to create or modify data models, consider using a different naming convention that does not start with X, Y, or Z. This will allow you to create and edit models without encountering this restriction.
  Development System: If you need to make changes to existing models that are restricted, you may need to do this in a development system where you have the necessary permissions and where custom developments are allowed.
  Transport Requests: If you have made changes in a development environment, ensure that you transport these changes to the appropriate systems (e.g., quality assurance, production) using transport requests.
  Consult Documentation: Refer to the SAP documentation for MDG to understand the implications of modifying data models and the best practices for naming conventions.
