• What is the cause and solution for SAP error message USMD1074 - Data model &1, entity type &2 has invalid higher-level entity types ?

  The SAP error message USMD1074 indicates that there is an issue with the data model configuration in the SAP Master Data Governance (MDG) system. Specifically, it points out that the specified data model and entity type have invalid higher-level entity types. This typically occurs when the hierarchy of entity types is not correctly defined or when there are inconsistencies in the relationships between the entity types.
  Cause:
  
  Incorrect Configuration: The higher-level entity types may not be correctly configured in the data model. This can happen if the entity types are not properly linked or if there are missing relationships.
  Data Model Changes: If there have been recent changes to the data model, such as adding or removing entity types, it may lead to inconsistencies.
  Transport Issues: If the data model was transported from one system to another, there may be issues with the transport that caused the hierarchy to become invalid.
  Custom Development: If there are custom developments or modifications in the data model, they may not align with the standard configurations.
  
  Solution:
  
  Check Data Model Configuration: Review the configuration of the data model in the SAP MDG system. Ensure that the higher-level entity types are correctly defined and that there are no missing links.
  Validate Relationships: Use the MDG data model maintenance tools to validate the relationships between entity types. Ensure that all higher-level entity types are correctly assigned to their respective lower-level entity types.
  Recreate or Adjust Entity Types: If necessary, recreate or adjust the entity types to ensure that they are correctly configured. This may involve deleting and re-adding entity types or adjusting their hierarchy.
  Transport Validation: If the issue arose after a transport, validate the transport logs and ensure that all necessary objects were transported correctly. You may need to re-transport the data model or manually adjust it in the target system.
