Smart SAP Assistant

• What is the cause and solution for SAP error message MDG_DT_DATA_MODEL132 - Models with Y*/Z* names cannot be deleted in delivery landscape ?

  The SAP error message MDG_DT_DATA_MODEL132 indicates that you are attempting to delete a data model that has a name starting with "Y" or "Z" in the delivery landscape. In SAP, models that start with these letters are typically custom models created by users or developers, and the system restricts the deletion of these models in the delivery landscape to prevent accidental loss of custom configurations.
  Cause:
  
  Custom Data Models: The error arises because the system is designed to protect custom data models (those prefixed with Y or Z) from being deleted in the delivery landscape. This is a safeguard to ensure that important customizations are not inadvertently removed.
  
  Solution:
  
  
  Check the Model: Verify if the data model you are trying to delete is indeed a custom model (Y/Z). If it is, consider whether you really need to delete it.
  
  
  Transport Request: If you need to delete the model, you may need to do so in the development environment and then transport the changes to the quality or production environment. Ensure that you follow the proper transport procedures.
  
  
  Change the Model: If you want to modify or deactivate the model instead of deleting it, consider changing its status or configuration rather than deleting it outright.
  
  
  Consult Documentation: Review SAP documentation or consult with your SAP Basis or MDG team for best practices regarding the management of custom data models.
  
  
  SAP Support: If you believe that the deletion is necessary and you are encountering this error inappropriately, consider reaching out to SAP support for further assistance.

  By following these steps, you should be able to address the error message and manage your data models effectively within the SAP environment.
