• What is the cause and solution for SAP error message DMU107 - Node type &1 of node &2 does not allow subnodes ?

  The SAP error message DMU107 indicates that you are trying to add a subnode to a node type that does not support subnodes in the context of the Data Migration Workbench (DMW) or similar data management tools in SAP. This typically occurs when you are working with a hierarchical structure where certain node types are not designed to have child nodes.
  Cause:
  
  Node Type Restrictions: The node type you are trying to add a subnode to is defined in the system as not allowing subnodes. This is often due to the nature of the data model or the specific configuration of the node type.
  Incorrect Hierarchical Structure: You may be attempting to create a hierarchy that does not conform to the predefined structure of the data model.
  Configuration Issues: There may be issues with the configuration of the data model or the way the nodes are defined in the system.
  
  Solution:
  
  Check Node Type Definition: Review the definition of the node type in the data model to confirm whether it is indeed set to allow subnodes. You may need to consult the data model documentation or the configuration settings.
  Use Correct Node Type: If you need to create a subnode, ensure that you are using a node type that supports subnodes. You may need to change the node type you are working with.
  Adjust Hierarchical Structure: Reassess the hierarchical structure you are trying to create. Ensure that you are following the correct parent-child relationships as defined in the data model.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the specific node types and their capabilities within the context of your data migration or management task.
  Seek Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide assistance based on your specific configuration and requirements.
