• What is the cause and solution for SAP error message MDG_DT_DATA_MODEL048 - &1 data model is in Customer namespace; do not use Z*,Y*, or X* ?

  The SAP error message MDG_DT_DATA_MODEL048 indicates that you are trying to create or modify a data model in the Master Data Governance (MDG) system that is in a customer namespace (typically starting with Z, Y, or X*). The error message is essentially a warning that you should not use these namespaces for data models that are intended to be part of the standard MDG framework.
  Cause:
  
  Namespace Violation: The error occurs because the data model you are trying to create or modify is in a customer namespace (Z, Y, or X*), which is not allowed for certain MDG objects. SAP restricts the use of these namespaces to ensure that standard functionality is not compromised and to maintain the integrity of the MDG framework.
  Configuration Error: It may also arise from incorrect configuration settings or an attempt to customize standard MDG data models in a way that is not supported.
  
  Solution:
  
  Use Standard Namespace: Ensure that you are using the standard namespace for your data model. Standard namespaces typically do not start with Z, Y, or X. You should create or modify your data model in the standard namespace provided by SAP.
  Review Data Model Requirements: Check the requirements and guidelines for creating data models in MDG. Make sure that you are following the best practices and recommendations provided by SAP.
  Consult Documentation: Refer to the official SAP documentation for MDG to understand the limitations and guidelines regarding data models and namespaces.
  Contact SAP Support: If you believe that your use case is valid and should be allowed, consider reaching out to SAP support for further assistance or clarification on the restrictions.
