  The SAP error message USMD1611 indicates that you are trying to delete a field from a model entity that is generated and cannot be deleted. This typically occurs in the context of SAP Master Data Governance (MDG) when working with data models and entities.
  Cause:
  The error arises because:
  
  The entity type you are trying to modify contains fields that are generated by the system, which are essential for the integrity and functionality of the data model.

  Identify Generated Fields: Check the entity type mentioned in the error message to identify which fields are generated. You can do this by reviewing the data model in the SAP MDG configuration.
  
  
  Review Model Configuration: Ensure that you are not attempting to delete fields that are necessary for the model's operation. If you need to make changes, consider whether you can hide the field instead of deleting it.
  
  
  Modify Field Properties: If you need to change the behavior of the generated fields, consider modifying their properties (e.g., making them optional) rather than deleting them.
  
  
  Consult Documentation: Refer to the SAP MDG documentation for guidelines on managing data models and entities. This can provide insights into which fields are generated and how to handle them.
  
  
  Seek Help from SAP Support: If you are unsure about the implications of deleting a generated field or if you believe there is a mistake, consider reaching out to SAP support or your internal SAP team for assistance.
