  The SAP error message USMDZ3271 indicates that there is an issue with the structure of the data model in the context of SAP Master Data Governance (MDG). Specifically, this error occurs when you attempt to create or modify a hierarchy in a way that is not allowed by the system's rules regarding consolidation groups.
  Cause:
  The error message "USMDZ3271 &1 &2 Only consolidation groups are allowed underneath the root node" typically arises when:
  
  You are trying to add a node (such as a business partner, material, or other master data) that is not a consolidation group directly under the root node of a hierarchy.
  The hierarchy structure is not correctly defined according to the rules of the MDG configuration, which expects only consolidation groups to be placed directly under the root node.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Hierarchy Structure: Review the hierarchy structure you are trying to create or modify. Ensure that only consolidation groups are placed directly under the root node.
  
  
  Modify the Node Type: If you have mistakenly added a non-consolidation group node under the root, you will need to either:
  
  Move the node to a valid position in the hierarchy where it is allowed.
  Change the node type to a consolidation group if applicable.
  
  
  
  Consult Documentation: Refer to the SAP MDG documentation for guidelines on hierarchy structures and the specific requirements for consolidation groups.
  
  
  Use the Correct Transaction: Ensure you are using the correct transaction or application for managing the hierarchy. Sometimes, using the wrong tool can lead to structural issues.
  
  
  Check Configuration Settings: If you have access to the configuration settings, verify that the settings for hierarchy management and consolidation groups are correctly configured.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP team for further assistance.
