• What is the cause and solution for SAP error message USMD1122 - Data model &1: SAP packages can be changed only in SAP's own systems ?

  The SAP error message USMD1122 indicates that you are trying to make changes to SAP standard packages in a system that is not an SAP development system. This error typically occurs in the context of the SAP Master Data Governance (MDG) application when you attempt to modify data models or related objects that are part of the standard SAP delivery.
  Cause:
  The error arises because:
  
  SAP standard packages are protected from modification in non-development environments (like production or quality assurance systems) to ensure system integrity and stability.
  Changes to standard packages should only be performed in a development environment where you can transport changes through the proper channels.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the System Type: Ensure that you are in a development system (e.g., a sandbox or development environment) where modifications to standard packages are allowed.
  
  
  Use Custom Packages: Instead of modifying standard SAP packages, create your own custom packages. This is the recommended approach for any enhancements or modifications. You can then implement your changes in these custom packages.
  
  
  Transport Changes: If you need to transport changes to other systems (like QA or Production), ensure that you follow the proper transport procedures. Changes made in a development system can be transported to other systems using the SAP Transport Management System (TMS).
  
  
  Consult Documentation: Review the SAP documentation related to the specific data model you are working with. This can provide insights into best practices and guidelines for making changes.
  
  
  Contact SAP Support: If you believe you are in the correct environment and still encounter this error, consider reaching out to SAP support for further assistance.
