• What is the cause and solution for SAP error message MDG_GN011 - Blueprint &1 must be a global class - system error ?

  The SAP error message MDG_GN011 indicates that a blueprint (or a class) you are trying to use in the Master Data Governance (MDG) context must be a global class. This error typically arises when the system expects a global class but encounters a local class instead.
  Cause:
  
  Class Scope: The class you are trying to use is defined as a local class (i.e., it is defined within a specific program or function group) rather than a global class. In SAP ABAP, local classes are not accessible outside their defining program or function group.
  Configuration Issues: There may be configuration issues in the MDG setup that are causing the system to look for a global class that is not defined or incorrectly referenced.
  
  Solution:
  
  
  Check Class Definition:
  
  Go to the ABAP Workbench (transaction SE80 or SE24) and check the class definition. Ensure that the class is defined as a global class.
  If it is a local class, you will need to either convert it to a global class or create a new global class that meets the requirements.
  
  
  
  Modify the Class:
  
  If you have access to the ABAP code, you can modify the class definition to make it global. This typically involves changing the class definition from CLASS <local_class> DEFINITION to CLASS <global_class> DEFINITION and ensuring it is placed in a package that is not local.
  
  
  
  Check MDG Configuration:
  
  Review the MDG configuration settings to ensure that all required classes are correctly defined and referenced. This may involve checking the MDG customizing settings in transaction MDGIMG.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to MDG and the specific blueprint you are working with. There may be specific requirements or known issues documented by SAP.
  
  
  
  Contact SAP Support:
  
  If you are unable to resolve the issue, consider reaching out to SAP support for assistance. Provide them with the error message and any relevant details about your configuration and the steps leading to the error.
  
  
  
  Related Information:
  
  Global vs. Local Classes: Understanding the difference between global and local classes in ABAP is crucial. Global classes can be accessed from anywhere in the system, while local classes are restricted to their defining program or function group.
  MDG Configuration: Familiarize yourself with the Master Data Governance configuration settings, as incorrect settings can lead to various errors.
  ABAP Development: If you are involved in ABAP development, ensure you follow best practices for class design and organization to avoid scope-related issues.
  
  By addressing the class scope and ensuring proper configuration, you should be able to resolve the MDG_GN011 error.
